Lecture 2- Basic of Neuroanatomy

Question 1

Diencephalon AKA

Answer 1

Thalamus

Question 2

what does the thalamus do

Answer 2

receives sensory info from cebral cortex

sorts info. ROUTER

sensory and motor signals

Question 3

Cerebellum functions

Answer 3

sensory integration, fine motor control, error based learning

voluntary movements, speech, balance, complex decisions

Question 4

spinal cord function

Answer 4

receives sensory info in and up to brain or sends motor info down stem and to limbs

Question 5

Brainstem parts and functions

Answer 5

Medulla
pons
mid brain

-

Question 6

sympathetic and parasympathetic systems

Answer 6

sympathetic- stress responses
para- rest and digest

While your sympathetic nervous system carries signals that put your body’s systems on alert, your parasympathetic carries signals that relax those systems.

Question 7

PERTERVATION

Answer 7

disturbance or external stimuli we react tp

Question 8

CNS and PNS

Answer 8

central nervous system brain and spinal cord

periphery nervous system everything else

Question 9

Afferent and Efferent

Answer 9

Nerve cells that carry information toward the central nervous system (or farther centrally within the spinal cord and brain) are called afferent neurons; nerve cells that carry information away from the brain or spinal cord (or away from the circuit in question) are called efferent neurons.

Question 10

How does info travel in the spinal cord

Answer 10

info in thru the back out thru the front

Question 11

where are the lumps in the spine and why

Answer 11

cervical and lumbar bc more nerves coming in and out to limbs

Question 12

grey and white matter

Answer 12

The grey matter is the place where the processing of sensation, perception, voluntary movement, learning, speech and cognition takes place. White matter’s role is to provide communication between different grey matter areas and between grey matter and the rest of your body.

Question 12

Ganglion

Answer 12

in the PNS collection of cell bodies

Question 13

Nucleus

Answer 13

in the CNS collection of cell bodies

Question 13

types of glial cells

AND function.

Answer 13

SAO
astrocytes- provide nutritional support for neurons and repair damaged ones
Schwann- myelinate neurons in the PNS wrap around an axon
oligodentrocytes- myelinate neurons in the CNS. form a web. SPIDERMAN

Question 14

dermatone

Answer 14

area of skin supplied by neurons

Question 15

NEURON

Answer 15

dendrites receive signals
axon send out and myelin make sure signals stay healthy

form follows function

myelin speed up electrical signal transfer

axon hillock is where you decide if an action potential occurs

Question 16

motor neuron

Answer 16

efferents
away from brain and in spinal cord
ventral horn

Question 17

sensory neuron

Answer 17

afferents and outside spinal cord

Question 18

Reciprocal inhibition

Answer 18

Reciprocal inhibition describes the relaxation of muscles on one side of a joint to accommodate contraction on the other side. In some allied health disciplines, this is known as reflexive antagonism. The central nervous system sends a message to the agonist muscle to contract

Question 19

Interneurons

Answer 19

As the name suggests, interneurons are the ones in between - they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons,
