Term
| major autonomic receptors |
|
Definition
Nn - micotinic receptors on cell bodies in ganglia of both PNS and ANS and in the adrenal medulla
Nm - nicotinic receptors on skeletal muscle motor end plate innervated by somatic motor nerves
M1-3 - muscarinic receptors located on all organs and tissues innervated by postganglionic nerves of PNS and on thermoregulatory sweat glands innervated by SNS |
|
|
Term
|
Definition
ganglia lie in two paraventral chains adjacent to the vertebral column
ACh-->Nn receptors |
|
|
Term
| parasympathetic NS ganglia |
|
Definition
ganglia are located near the organs they innervate
preganglionic neuron: ACh-->Nn receptor in effector organ |
|
|
Term
|
Definition
NT that actson are both nicotinic and muscarinic receptors in tissues that are innervated
all direct transmission from the CNS (preganglionic and motor) use ACh |
|
|
Term
| postganglionic NTransmission |
|
Definition
PNS uses ACh
ANS uses ACh, NE, or Epi |
|
|
Term
|
Definition
contraction of sphincter muscle causes pupillary constriction (miosis) in response to muscarinic stimulation
contraction of ciliary muscle causes accommodation for near vision |
|
|
Term
| muscarinic antagonism in the eye |
|
Definition
| mydriasis (pupil dilation) |
