BIO 4430 Lecture Notes - Lecture 5: Loose Connective Tissue, Endoplasmic Reticulum, Basal Lamina
Document Summary
___ ____ and ___ ____ reticulum are essential components involved in skeletal muscle contraction. Because they are much longer than they are wide, muscle cells frequently are called muscle ____; unlike collagen fibers, however, they are living entities. _____ cell sits on individual axons and wraps itself around it completely. The center of each a band is occupied by a pale area, the h band, which is bisected by a thin ____ _____ Centrally located nuclei with halo, has intercalated disks, vacuole-like holes in cells composed of reticular fibers and an external lamina (basal lamina), surrounds each muscle cell (fig. Sr (ryanodine receptor) & ca2+ channel in plasma membrane. Ct that is wrapped around each individual axon. Ct that is wrapped around individual bundles of axons. The dark bands of skeletal muscles are known as. Each i band is bisected by a thin dark line, the ___ ____ Z line epineurium endoneurium is made of loose connective tissue.
