week 4: neurobiology: autonomic and somatic NS overview

Question 1

somatic NS

Answer 1

how we control voluntary movements
skeletal muscles

Question 2

overview of somatic NS

Answer 2

neurones start in CNS
projects to ganglia- somatic motor nuclei of brainstem
motor neurones project from nuclei to skeletal muscle
produce neurotransmitters when they want skeletal muscles to contract

Question 3

upper mototr neurones

Answer 3

start at CNS and then innovate motor nuclei

Question 4

lower motor neurones

Answer 4

from motor nuclei to muscle

Question 5

what neurotransmitter do upper motor neurons and lower motor neurones release

Answer 5

acetylcholine

Question 6

motor neuron disease results from

Answer 6

degeneration of lower motor neurons or upper motor neurons or both
stops being able to take signal from CNS, process it to motor nuclei and push it onto muscle

Question 7

two halves of autonmic NS

Answer 7

sympathetic and parasympathetic

Question 8

overview of autonomic NS

Answer 8

neurons within CNS
project into nuclei in spinal cord
innovate other neurons
take message from spinal cord to autonomic ganglia
innovate postganglionic neurons
project from ganglia to target organs

Question 9

preganglionic neurons

Answer 9

neurons which go from spinal cord to autonomic ganglia

Question 10

postganglionic neurons

Answer 10

project from ganglia to target organs
