Background: The position and size of isthmus of thyroid vary greatly in humans, and sometimes it is absent. The present study was designed to find out the difference in isthmus of the thyroid gland of Bangladeshi people in relation to age and sex. Methods: The cross-sectional, descriptive study was performed in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2008, on 73 post mortem human thyroid gland collected from unclaimed dead bodies. Isthmus was found in 60 cases. The samples having the isthmus (n=60) were divided into three age-groups including group A (10-20 years), group B (21-50 years) & group C (>50 years) and the isthmus was cut off from the thyroid gland, then its length, breadth and thickness were measured and recorded. Results: The isthmus of the thyroid gland was found in 82.2% cases. It extended from 2nd to 4th tracheal ring in 91.7% and from 2nd to 5th ring in 8.3% cases. No difference was found in length, breadth and thickness of the isthmus of the thyroid gland in between males and females. However, difference was found in breadth between group A & B (p<0.05) and A & C (p<0.01) and in thickness between group B & C (p<0.05). Conclusion: The presence or absence, positional change and variation in gross dimension of the thyroid isthmus were evident in humans. The morphological difference was found with increasing age but not with sex.

Context: The thyroid gland is the first endocrine organ to evolve in the vertebrates. It has right and left lobes and connected by narrow median isthmus which lies over the second, third and fourth tracheal rings. A conical pyramidal lobe often ascends towards the hyoid bone from isthmus or the adjacent part of either lobe. It measures about 1.25 cm transversely and vertically. Its size and site vary greatly. Isthmus is topographically related with some important anatomical structures. So this study was carried out to determine the incidence of presence & variation in anatomical position of isthmus of thyroid gland of Bangladeshi people of different age groups to establish a normal standard. Study type: Descriptive cross-sectional study. Place and period of study: Department of Anatomy, Mymensingh Medical College. from October’2004 to February’2005. Materials: The study was carried out on 60 cadavers of different age groups age ranging from 11 to 70 years. Thyroid glands were collected from unclaimed dead bodies autopsied in Forensic Medicine Department of Mymensingh Medical College. Methods: The collected specimens were divided into age group A (upto 18 years), group B (18 to 45 years), group C (above45 years). All specimens were examined morphologically by fine dissection method. Result: In the present study isthmus was present in 41 (68.33%) cases. In those thyroids which were devoid of isthmus, lobes were found to be merged with each other in the midline but in one case two lobes were found completely separated from each other. It was evident that the posterior relations of isthmus were widely variable. In only 18% cases it was found at its usual position- against the 2nd, 3rd and 4th tracheal rings. In the present study more frequent location of isthmus was found at 1st, 2nd, 3rd and 2nd, 3rd, 4th tracheal rings. In both cases their incidences were 18.3%. Conclusion: The present study will help to increase the information pool on the anatomy of thyroid gland of Bangladeshi people. To establish a normal standard for Bangladeshi people, further studies with large samples from different zones of the country are suggested.

This cross sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka from January to December 2009, to determine the proportion of cortex and medulla of the ovary in di_erent age group of Bangladeshi women. This study was based on collection of 140 ovaries of 70 unclaimed female dead bodies from the morgue of Dhaka Medical College, Dhaka. The samples were divided into three age-groups including A (10-13 years), B (14-45 years) & C (46-52 years). Histological slides were prepared by using routine haematoxylin and eosin stain. Ten best prepared histological slides from each age group were examined to determine the thickness of the cortex and medulla & proportion of the thickness of the cortex and the medulla of the ovary were expressed in percentages. The mean proportion of the cortex and the medulla of the right ovary were found 80.83±0.58% and 19.17±0.58% in group A, 86.95±1.14% and 13.05±1.14% in group B, 70.53±1.53% and 29.47±1.53% in group C respectively. The mean proportion of the cortex and the medulla of the left ovary were found 80.63±0.58% and 19.37±0.58% in group A, 86.78±1.14% and 13.22±1.14% in group B, 70.41±1.50% and 29.59±1.50% in group C respectively. The difference in mean proportion of the cortex and the medulla was not signi_cant in between the ovaries. However, the difference in mean proportion of the cortex and the medulla of the ovary between group A & group B, group A & group C and group B & group C were statistically significant.Bangladesh Med J. 2015 Jan; 44 (1): 8-10

Background: The pyramidal lobe is also called the 3rd lobe of the thyroid gland which ascends toward the hyroid bone from the isthmus or the adjacent part of either lobe. A fibrous or fibromascular band the levetor glandulae thyroideae occasionally extends upwards from the apex of the pyramidal lobe to the body of the hyoid bone. Any pathology of thyroid gland involves this lobe, some pathology started from here or recurrence may occur from this lobe. Anatomical knowledge about pyramidal lobe is essential for surgeons, endocrinologists, pathologists and sonologists for proper diagnosis and management of thyroid diseases. Study design: Cross sectional descriptive type of study. Place and period of study: Department of Anatomy, Sir Salimullah Medical College, Dhaka. Study period was from July 2003 to June 2004. Materials: The study was done by examining 60 post mortem human thyroid glands, age ranging from 7 to 67 years. The glands were collected from unclaimed dead bodies autopsied in the morgue of Dhaka Medical College and Sir Salimullah Medical College under the department of Forensic Medicine. Methods: The collected sample were grouped in to three age groups including group A(0-20 years), group B (21-50 years) and group C (>50 years). The presence, variation of position of the pyramidal lobe and its relation with levator glandulae thyroideae were studied. Result: The pyramidal lobe was found in 16 of 60 thyroid glands in different age groups and situated more on the left side than the right. In 9 cases, levator glandulae thyroideae were found. All extended from the apex of the pyramidal lobe to the body of the hyoid bone. Key words: Pyramidal lobe; levator glandulae thyroideae; thyroid gland.

Background: The position and size of isthmus of thyroid gland varies considerably in human with age, sex, physiologic state, race and geographical location and sometimes the isthmus may be absent. So this study was designed to find out the macroscopic differences in isthmus of thyroid gland of different age and sex groups in Bangladeshi people.Objective: To record the macroscopic characteristics of isthmus of thyroid gland with advancing age in both sexes with a view to help establishing normal standard of Bangladeshi people.Materials and Methods: This descriptive cross-sectional study was carried out on 54 autopsied human thyroid glands aged 5 to 65 years. Thyroid glands were collected from unclaimed dead bodies autopsied in the morgue of Sylhet M. A. G. Osmani Medical College, Sylhet. The collected specimens were divided into groups –– A (20 years and below), B (21 to 50 years) and C (50 years and above). All specimens were examined morphologically by careful gross dissection method.Results: The isthmus was absent in 5.56% cases. In most of the cases (35.29%) it was against the 1st–4th tracheal rings. There was significant difference in length between Group A and Group C (p<0.05) and in breadth between Group A and Group C and between Group B and Group C (p<0.05). No significant difference was found in length, breadth and thickness of isthmus of the thyroid gland between males and females.Conclusion: The presence or absence, positional change and variation in gross dimension of isthmus of thyroid gland were evident in human. The macroscopic difference was found with increasing age but not with sex.J Enam Med Col 2017; 7(1): 15-19

Context: The central sulcus, which is located between the primary motor and primary somatic sensory cortex is an important structure and landmark of the cerebral hemisphere. Morphology of the central sulcus varies with age, sex, manual skill, handedness and in many diseases. This study is carried out to establish a normal standard in different age groups in length and depth of the central sulcus. Materials and Methods: A cross-sectional, analytical type of study was conducted in the department of Anatomy, Dhaka Medical College, on one hundred and forty (140) on human cerebral hemispheres. The samples were divided into four different age groups i.e. Group A (20-29 years), Group B (30-39 years), Group C (40-49 years) and Group D (50-59 years). All the samples were studied morphologically. Results: The mean length of central sulcus was 102.89±3.55 mm to 96.83±3.92 mm in male and 98.00±5.17 mm to 96.29±2.56 mm in female. Depth of the central sulcus was 20.02±2.41 mm to 21.50±2.21 mm in male and 20.50±2.57 mm to 21.36±1.87 mm in female. The difference in mean length of the right central sulcus between male and female was statistically significant in group A (p<0.05) and B (p<0.05). The difference in mean depth of the central sulcus between male and female was not statistically significant in any age groups. No significant difference was found between right and left hemisphere for both length and depth of the central sulcus. The difference in mean length and depth of the central sulcus between different age groups for both left and right hemisphere was not statistically significant in any age group. Conclusion: The length and depth of the central sulcus showed gradual decreasing values with advancing age.

Reproductive age, ovarian reserve and reproductive capability may be determined from the volume of the ovary. A cross-sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2009, to see the variation in the volume of the ovary with age in Bangladeshi women. The study was performed on 140 post mortem human ovaries collected from 70 unclaimed female dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age-groups including group A (10-13 years), group B (14-45 years) & group C (46-52 years). Group A is pre-menarche group, group B represents reproductive age and group C is post menopausal group. The length, breadth and thickness of each ovary were measured by using a slide calipers. Then the volume of each ovary was determined by the product of its length, breadth and thickness multiplied by 0.524, according to the Prolate ellipsoid formula. The mean volume of the right ovary was found higher than that of the left one in all age groups (p<0.001). The difference in mean volume of the ovary between group A & group B, group B & group C (p<0.001) and group A & group C (p<0.01) were also statistically significant. The volume of the ovary increases with age and then gradually starts to decrease from menopause. DOI: http://dx.doi.org/10.3329/bmrcb.v40i1.20323 Bangladesh Med Res Counc Bull 2014; 40: 15-17
