Muscle is a soft tissue found in most animals, and is one of the four basic animal tissues , along with nervous tissue , epithelium , and connective tissue. Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture , locomotion , as well as movement of internal organs , such as the contraction of the heart and the movement of food through the digestive system via peristalsis. Muscle tissue is derived from the embryonic mesodermal germ layer in a process known as myogenesis.

Skeletal/Muscular Case Studies
Forensic facial reconstruction or forensic facial approximation is the process of recreating the face of an individual whose identity is often not known from their skeletal remains through an amalgamation of artistry, anthropology , osteology , and anatomy. It is easily the most subjective—as well as one of the most controversial—techniques in the field of forensic anthropology. Despite this controversy, facial reconstruction has proved successful frequently enough that research and methodological developments continue to be advanced. In addition to remains involved in criminal investigations, facial reconstructions are created for remains believed to be of historical value and for remains of prehistoric hominids and humans. There are two forms pertaining to identification in forensic anthropology : circumstantial and positive.

We tested the hypothesis that deep-sea fishes have poorly mineralized bone relative to shallower-dwelling species using data from a single family that spans a large depth range. We used micro-computed tomography micro-CT scanning to test three aspects of skeletal reduction in snailfishes 50 species across a full range of habitat depths: 1 reduction of structural dimensions, 2 loss of skeletal elements, and 3 reduction in bone density. Using depth data from the literature, we found that with increasing depth, the length of the dentary, neurocranium, and suborbital bones decreases.
