- NMBA's are important at what portion of the nervous system?
- Somatic Nervous System
- Motor neurons to the skeletal muscles originate where?
- Anterior or Ventral horn of spinal cord
- Motor neuron are what type of neurons?
- EFFERENT neurons
- Sensory neurons from skeletal muscles carry AP to spinal cord via?
- Dorsal horn
- Motor and Sensory motor neurons are considered what type of nerves?
- Somatic nerves
- Motor nerves are ___________ and will exit the ____________ of spinal cord/
-
Efferents
Ventral cord - Sensory nerves are _________ and will exit the _____________.
-
Afferent
dorsal posterior cord - What causes the release of Ach at the presynaptic membrane?
- Calcium
- Motor nerves release _________ to the motor endplate on the ____________ side of neuron.
-
Ach
Postsynaptic side - What other receptors are found in the post synaptic membrane with Ach receptors?
- Nicotinic receptors
- This is found in clos proximity to post synaptic icotinic receptors, and extend into synaptic cleft to metabolize Ach.
- Acetylcholineesterase
- This enzyme brakes down Ach on postsynaptic membrane, stoping an action potential.
- Acetylcholinesterace
- The nicotinic cholinergic receptors is composed of what?
- 5 glycoprotein subunits
