BIOL 030 Lecture Notes - Lecture 19: Pharyngeal Arch, Myod, Mastication
Document Summary
Note basically, when a muscle passes over a joint it will play a part in moving it. Lateral intermuscular septum between radius and deep fascia. Interosseous membrane between radius and ulna. Medial intermuscular septum - between ulna and deep fascia. Note superficial muscles have origin on medial epichondyle or humerus or proximal-anterior radius/ulna. Define and describe the location of three types of muscle tissue: skeletal, cardiac and smooth. List and describe the differences between the developmental origins for the skeletal muscle of the body: trunk muscles, pharyngeal arch muscles, ocular muscles, tongue muscles and muscles of the limbs. Define and/or describe: epaxial musculature, hypaxial musculature. Describe the process of muscle cell maturation. List the major regulatory factors that influence muscle cell maturation. List/describe the origin of cardiac and smooth muscle. Initial formation of the muscular system is independent from skeletal system, but later maturation is closely tied. Fusion of mononucleated precursors to form multinucleated fibers.
