WebbThe constituents of the tunica muscularis varies based on species and location along the length of the esophagus. For example, in species such as the cat and horse, the tunic muscularis is primarily composed of skeletal muscle with distal segments incorporating smooth muscle. Dogs and ruminants have uniform skeletal muscle along the entire length. WebbSkeletal muscle cells contain similar components and structures as other cells but different terms are used to describe those components and structure in skeletal muscle cells. The plasma membrane of skeletal muscle is called the sarcolemma; its cytoplasm is known as sarcoplasm; the endoplasmic reticulum is called the sarcoplasmic reticulum.
