ABSTRACTDuring dissection of a 55-year-old female cadaver, we observed that three nerve roots contributed to the formation of Median nerve in her right upper limb. Along with this variation, absence of Musculocutaneous nerve was noticed. The muscles of front of arm i.e. Biceps Brachii, Brachialis and Coracobrachialis received their nerve supply from Median nerve. The Lateral cutaneous nerve of forearm was derived from Median nerve. Also an accessory head of Biceps Brachii muscle was present in the right arm of the same cadaver. It is extremely important to be aware of these variations while planning a surgery in the region of axilla or arm as these nerves are more liable to be injured during operations.

AbstractVariations in the distribution of the lateral cord and its branches in the infraclavicular part of the brachial plexus are common and significant to the neurologists, surgeons, anaesthetists and the anatomists [1]. The present case describes a rare variation of the lateral pectoral nerve giving an additional branch to supply biceps brachii muscle and ends by joining inferior collateral branch of brachial artery. Also it was observed that the musculo cutaneous nerve received communicating branches from the median nerve before and after piercing the coracobrachialismuscle. The above observations were observed during routine dissection of a 55 year old Indian male cadaver. The musculocutaneous nerve, lateral pectoral nerve and its branches were identified and protected. The clinical importance of the variation is discussed.

AbstractMany authors have reported and classified several anatomical variations between the musculocutaneous (Mc) and median (Me) nerves, regarding their origin, number, and proximity with the coracobrachialis muscle. There also are, in the scientific community, records classifying the origin of supernumerary heads of the biceps brachii muscle. However, the occurrence of both aforementioned variations in the same arm is very uncommon. During a routine dissection of the right upper limb of a male cadaver, a third head of the biceps brachii was found originating from the fibers of the brachialis muscle, as well as a communicating branch between the Mc and the Me nerves, in the same limb. The objective of the present case report is to describe these multiple variations found, relating them and discussing their relevant clinical implications.

Abstract Background and aims : The biceps brachii is the large muscle of flexor compartment of arm. Normally it arises by two heads (long head and short head) and gets insertion in two parts (tendinous part and aponeurotic parts). The biceps brachii muscle is well known for variation in its origin. These variations can cause compression of brachial artery and median nerve which may pass deep to the accessory head of biceps brachii muscle, and can create problems for surgeons. So the surgeons should keep in mind such variations of biceps brachii muscle. The present study is to find out the variations in the origin of biceps brachii muscle. Material and methods: The present study was conducted in the department of anatomy of Gian Sagar Medical College, Ramnagar, Rajpura district Patiala (Punjab). In this study 32 human cadaveric limbs which were embalmed and fixed in 10% formaldehyde solution were used and these limbs were dissected and variations in origin of the biceps brachii muscle were noted. Results : Out of 32 limbs, 3 limbs (9.38%) were having three heads of biceps brachii muscle in its origin. The variations were found in the right limbs only. Conclusions : The knowledge of accessory head of biceps brachii muscle is important for the surgeons and troumatologists because there can be iatrogenic injury to the third head of biceps brachii muscle.

AbstractBiceps brachii muscle is very variable. Biceps may be composed of one to five heads. Although the variations in the origin are plenty, there are a very few cases reported on the variations in the insertion of the biceps brachii muscle. In this report we present a variant biceps brachii muscle which gives an abnormal muscle fasciculus from its medial side which continues as a narrow tendinous slip and is inserted in to the medial supracondylar ridge of humerus. We discuss in this report, the possible median nerve entrapment due to the presence of such a variation.

AbstractThe coracobrachialis muscle (CBM) originates from the apex of the coracoid process, in common with the short head of the biceps brachii muscle, and from the intermuscular septum. The CBM demonstrates variability in both the proximal and distal attachment, with some extremely rare varieties, such as the coracobrachialis superior, coracobrachialis longus and coracocapsularis muscle. This case report describes an extremely rare variant of the coracobrachialis superior muscle, or a very rare variant of the CBM. Our findings highlight the importance of muscle variants in the shoulder region, especially the coracoid region, and are significant for radiologists, anatomists, physiotherapists and surgeons specializing in the shoulder joint.
