Forty percent of your body mass is made up of skeletal muscle. 5. Cardiac muscle fibers cells also are extensively branched and are connected to one another at their ends by intercalated discs. Smooth muscle and cardiac muscle move to facilitate body functions like heartbeats and digestion. Sternocleidomastoid Skeletal muscle is attached to bones and its contraction makes possible locomotion, facial expressions, posture, and other voluntary movements of the body. Smooth muscle lines the walls of blood vessels and certain organs such as the digestive and urogenital tracts, where it serves to advance the movement of substances. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth (Table 4.2). Anatomy & physiology i bis 240: bone model. This section is a bit of a hodge-podge. The head muscles are an interesting group because they have many specific functions but are usually grouped into two large categories- facial muscles and chewing muscles. Kenhub. as well as other congenital, inflammatory or metabolic myopathies. The buccinator muscle, which is a member of this group, is described with the facial muscles. Shivering is an involuntary contraction of skeletal muscles in response to perceived lower than normal body temperature. It can recoil back to its original length due to elastic fibers.

The muscles of the lower limb that causes movement of the knee joint are: Muscles Causing Movement at the Ankle and Foot. Because the actin and myosin are not arranged in such regular fashion in smooth muscle, the cytoplasm of a smooth muscle fiber (which has only a single nucleus) has a uniform, nonstriated appearance (resulting in the name smooth muscle). They are contractile, meaning they can shorten and generate a pulling force. D. Muscles Muscle fibers Fasciculus Myofibrils Myofilaments, 10. Forty percent of your body mass is made up of skeletal muscle. Muscle cells are excitable; they respond to a stimulus. 9.1: Introduction to Muscle Tissue When most people think of muscles, they think of the muscles that are visible just under the skin, particularly of the limbs. Moore and A.F Dalley: Clinically Oriented Anatomy, 4th edition, (1999), p.26-32. 10. Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. Kissing muscle This broadness, and the interdigitations of the cardiac muscle increase its surface area for impulse conduction. Its to contract aids in the smooth movement of bones. When attached between two movable objects, in other words, bones, contractions of the muscles cause the bones to move. D, A, G, E, B, F, C This occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (Ca++) and proteins (troponin and tropomyosin) that shield the actin-binding sites.

The third group includes the muscles of the forearm. K.L. The striation is due to the regular alternation of the contractile proteins actin and myosin, along with the structural proteins that couple the contractile proteins to connective tissues. Innervation, like that of the smooth muscle, is by the autonomic nervous system (ANS). While the nervous system can influence the excitability of cardiac and smooth muscle to some degree, skeletal muscle completely depends on signaling from the nervous system to work properly. Bed-ridden people can undergo significant muscle wasting. C. temporalis, pterygoid, and 2 pairs of masseter D. Rectus abdominis. 0. Only two neck muscles are considered here.
