Wk8 Autonomic Sensory Components

Question 1

What are autonomic sensory components?

Answer 1

• receptors
  Viscera(soft tissues in body) - not consciously perceived e.g. baroreceptors (BP)
  Somatosensory/external environment - touch, where your limbs are in space
• somatic and autonomic integration

Question 2

What are autonomic motor components?

Answer 2

Different to somatic:

1. Effectors innervated
2. No. neurones between CNS & effector
3. Neurotransmission

Question 3

What does the SNS and PNS do?

Answer 3

• homeostasis + vision, reproduction
• SNS alert and active - fight and flight but also other things
• PNS rest & digest
  Para = longer = sloths take more time = rest

Question 4

What is dual innervation?

Answer 4

Not antagonistic - exocrine glands

Question 5

What is single innervation?

Answer 5

E.g. sweat glands - SNS only
E.g. most blood vessels
—> vasomotor tone
Smooth muscle = SNS only
