Indirect muscle attachment: epimysium, perimysium, endomysium role.
Function of muscle tissue
ANS and SNS related to CNS
Location of nicotinic receptors
Adrenergic versus cholinergic neurons, what neurotransmitters do they use?
Dorsal versus ventral spinal chord, which is sensory which is motor
Action potential at synaptic cleft is indirectly or directly responsible for neurotransmitter
exocytosis?
Epimysium, perimysium, endomysium what is where?
Function of muscle versus nervous tissue, differences
What is the CNS/PNS composed of/what structures (brain etc.)?
Direction of Afferent versus Efferent neuronal signaling
Striations exist in some muscles not in others, some muscles are voluntary others involuntary
Location of smooth muscle in the body
Dendrites contain recptors
Muscle is surrounded by arteries, veins and nerves?
Role of tropomyosin/troponin
Role of ATP hydrolysis in myosin-actin cross bridge formation
Myelination of nerve fibers is done by what type of glial cell (CNS versus PNS)?
Bacterial invasion of CNS….what glial cells are responsible in handling this problem?
Role of ependymal cells
