Ventral spinal cord

Question 15

Major locations of ach

Answer 15

Autonomic ganglia
Parasympathetic postganglionic synapses
Nmj
Renshaw cells of the spinal cord

Question 16

Renshaw cell

Answer 16

Inhibitory interneuron in gray matter of spinal cord

1. Receive excitatory collateral from alpha neuron as they emerge from motor root and are kept informed of how vigorously neuron is firing
2. send inhibitory axon to synapse with cell body lf alpha neuron

Negative feedback system
Target of clostridium tetanii

Question 17

Target of clostridium tetanii

Answer 17

Renshaw cells

Question 18

Clostrodium tetanii mechanism of action

Answer 18

Inhibits release of glycine, an inhibitory neurotransmitter, from Renshaw cells. Therefore alpha motor neurons become hyperactive and muscles spontaneously contract

Question 19

Strychnine poison mechanism of action

Answer 19

Acts on Renshaw cells preventing their ability to control alpha neurons firing by binding to glycine on alpha motor neuron. Muscles continually contract and its fatal if diaphram is involved

Question 20

Roles of AcH

Answer 20

Thermal receptors
Chemoreceptors
Taste
Pain receptors maybe

Question 21

Ach excitatory or inhibitory?

Answer 21

Excitatory
