Lab 3 Muscle/Nerve Tissue Flashcards
neuron
cell part of the nervous system that transmits electrical signals, contains processes called axons and dendrites that conduct the electrical impulses
axon
process of a neuron that propagates action potentials away from the cell body
dendrite
process of a neuron where graded potentials are initiated
glial cell
nervous system cells that support neurons. more numerous than neurons
skeletal muscle
fibers striated, tubular, and multi nucleated
smooth muscle
fibers non-striated, spindle shaped, and uninucleated
cardiac muscle
fibers striated, branched, and uninucleated
intercalated disc
intercellular junction between cardiac muscle cells composed of desmosomes and gap junctions that mechanically and electrically link these cells. found in cardiac muscle
