A & P: Nervous System

A

Cell body

How to Classify Neurons?

\# of processes from cell body, functions

Which cells indicate an infection of the CNS

Microglia

Motor

activates muscle

Sensory

detects a change

somatic

voluntary muscle control

autonomic

involuntary muscle control

Afferent

sends impulses to CNS

Efferent

Sends impulse from CNS

Transmission of the impulse

dendrites, cell body, axon

What is a synapse

A synapse is a junction between 2 neurons

What is resting potential

cell is negatively charged, environment is positively charged

Which lobe of the brain controls visual processing

Occipital lobe

Function of the Brainstem

sits above the spinal cord, controls involuntary activities

Function of the thalamus

relays sensory impulses to the PNS for processing

Role of the Frontal lobe

voluntary movement, reasoning and decision making, memory

Parietal lobe roles

sensations like pain and temp, visual spatial processing,

Occipital lobe

vision and memory of objects

temporal lobe roles

emotional association

cerebellum

movement and maintaining balance, muscle memory

cerebrum

divided into 2 hemispheres

What part of the nervous system can calm someone down after an emergency

Parasympathetic division

gyrus

hill on the brain

order of meninges

dura matter, arachnoid, pia mater

the cerebral cortex is not

made up of myelinated axons

Sensory division is also known as the -------------- division

afferent

function of fissure

seperates lobes of the brain, deep groves

controls pituitary gland and autonomic processes
