The skeleton provides the framework and anchor points against which muscles, attached via tendons, can exert force. Three types of cells are involved in making bone: osteoblasts, osteoclasts, and cartilage. The human muscle system is made up of three types of muscle tissue: skeletal, cardiac, and smooth. The neonate period of life is the first 4 weeks after the birth of an infant. This chapter presents 11 genetic disorders that affect muscles, connective tissue, and newborns. These include achondroplasia, Charcot-Marie tooth syndrome, Duchenne Muscular Dystrophy, Ellis-Van Creveld syndrome, amyotrophic lateral sclerosis, Marfan syndrome, fibrodysplasia ossificans progressive, myotonic dystrophy, Angelman syndrome, Prader-Willi syndrome, fragile-X syndrome, and Waardenburg syndrome.

A 12-year-old Irish sports horse gelding presented with a recently developed oval firm mass at the plantaromedial aspect of right tarsus, located between the gastrocnemius and deep digital flexor tendon. At presentation, the horse was mildly right hind lame, with no exacerbation with flexion. Radiography and ultrasonography revealed an ovoid mineralised mass within soft tissues plantaromedially to tarsus and distal tibia and not associated with tarsal sheath or calcaneal bursa. Due to mild intermittent lameness and concerns regarding possibility for further increase in size, the horse underwent en bloc removal of the calcified mass under general anaesthesia. Histopathology showed the mass contained fibrous reactive connective tissue, undergoing bone and cartilage metaplasia and degeneration, with a central area of calcified bone and surrounding region of mononuclear inflammation. These characteristics although reminiscent of calcinosis circumscripta were diagnosed as focal dystrophic calcification. The horse made a full recovery and returned to a normal exercise level.

Examination of the genitalia of male bobcats collected in Arkansas revealed the common occurrence of bacula. The preformed architecture of dense connective tissue and cartilage was evident in juveniles (<1 year). Observed morphological variation in adults was partially ascribed to ontogeny. Maximum dimensions observed were 7.6 mm (length) and 3.1 mm (width). The distal portion of the baculum is a narrow shaft, while the proximal region is expanded and bifurcated ventrally. A vertical septum separates two vacuities in the base of the baculum. These vacuities house the primarily adipose ends of the corpora cavernosa. Morphology of the baculum of the bobcat is similar to that of the European lynx, and, while different from other felids, it indicates validity of the genus Lynx.

Industrial processing of bovine hides into leather results in many unusable hide off-cuttings, shavings and trimmings. This waste raw material is under-utilised and presents a waste valorisation opportunity to derive a high-value product such as collagen. Collagen is a highly sought-after protein which consists of three polypeptide chains, comprising 30% of the mammalian body’s protein, being the main component of skin, connective tissue and cartilage. The demand for collagen is rising at approximately 20% annually and global collagen-based biomaterials market is predicted to reach US$5 billion by 2025. This chapter presents a waste valorisation opportunity to extract collagen from waste bovine hide off-cuttings. Further, it discusses collagen extraction method optimization and methods used to investigate physicochemical properties of collagen are reviewed.
