Autonomic Nervous System Flashcards

1
Q

What does it mean to say motor neurons have dual motor control in autonomic nervous system?

A

Many organs have both parasympathetic and sympathetic nerve supply which both are motor controls that tend to act in opposite ways

Q

What is the pathway of the sympathetic axon when it exits lateral horn?

A

Lateral horn -> anterior rootlet and roots -> spinal nerve -> anterior rami -> exits this through white rami -> joins sympathetic chain

Q

What are the 4 routes the presynaptic sympathetic axon can take once it enters sympathetic trunk?

A
  1. Ascend and synapse
  2. Synapse at level of entry
  3. Descend and synapse
  4. Pass through trunk without synapse and another abdominopelvic splanchnic nerve

Q

What part of gut do postsynaptic sympathetic axons from celiac ganglion innervate?

A

Foregut

17
Q

What part of gut do postsynaptic sympathetic axons from aorticorenal ganglion innervate?

A

kidney

18
Q

What part of gut do postsynaptic sympathetic axons from superior mesenteric ganglion innervate?

A

Midgut

19
Q

What part of gut do postsynaptic sympathetic axons from inferior mesenteric ganglion innervate?

A

Hindgut and pelvic/perineal organs

20
Q

What is significant about the presynaptic sympathetic axon to the adrenal medulla and what is its pathway?

A

only sympathetic nerve that doesn’t synapse till its at the organ,
passes through sympathetic trunk -> passes through aorticorenal ganglion (1 of the paravertebral ganglia) to synapse directly onto the adrenaline/noradrenaline secreting cells of adrenal medulla

21
Q

Craniosacral outflow and thoracolumbar outflow - which is sympathetic and which is parasympathetic?

A
  • craniosacral -> parasympathetic

- thorocolumbar -> sympathetic

22
Q

What cranial nerves and what sacral vertebral levels do parasympathetic nerves leave at?

A
  • Cranial nerves III, VII, IX and X

- S2, S3, S4

23
Q

Where does presynaptic parasympathetic axon from CN III synapse and what does it supply?

A
  • ciliary ganglion

- supplies iris and ciliary muscles

24
Q

Where does presynaptic parasympathetic axon from CN VII synapse and what does it supply?

A

-pterygopalatine ganglion (supplies lacrimal, nasal, palatine, pharyngeal glands) and submandibular ganglion (supplies sublingual and submandibular glands)

25
Q

Where does presynaptic parasympathetic axon from CN IX synapse and what does it supply?

A
  • Otic ganglion

- supplies parotid gland

26
Q

Where does presynaptic parasympathetic axon from CN X synapse and how far does it supply?

A
  • at the organs themselves

- as far as midgut (ends at splenic flexure of colon)

27
Q

Where does presynaptic parasympathetic axon from S2,S3 and S4 synapse and what does it supply?

A
  • synapse at organs

- supplies Hindgut, pelvis and perineum
