Q

Peripheral NS

A
  • communication from body’s organs, glands and muscles to the CNS
  • including info from outside world (sensory neurons) and from inside world (pains)
  • communication from CNS to body’s organs, glands and muscles via motor neurons
  • two sub divisions Somatic NS and Aotonomic NS
17
Q

Motor neurons (nerves)

A
  • neurons that communicate messages from CNS to particular muscles that organism intents to move
  • also known as efferent neurons
  • in Somatic NS
18
Q

Sensory Neurons (nerves)

A
  • a neuron that carries info from body and outside world into CNS
  • in Somatic NS
19
Q

Somatic NS

A
  • responsible for voluntary movement of Skeletal muscles.
  • motor neurons communicate from CNS to muscles intended to move
  • interaction with environment
20
Q

Autonomic NS

A
  • responsible for communication of info between CNS and body’s non skeletal muscles
  • and interaction with internal organs and glands
  • operates without voluntary control or conscious awareness
21
Q

Fight, flight or freeze response

A
  • sympathetic NS emergency system
  • active when organism perceives danger or in time of stress
  • readies body for action eg running away, fighting the threat or remaining
22
Q

Homeostasis

A
  • Normal bodily functions
  • relatively calm
  • parasympathetic NS maintains body’s metabolic balance durning times of low arousal and no threat
23
Q

Parasympathetic NS

A
  • branch of Autonomic NS
  • responsible for maintaining day to day functioning
  • responsible for most automatic functions of the body
  • digestion, heart rate, breathing etc
  • homeostasis
24
Q

Sympathetic NS

A
  • branch of autonomic NS

- activates flight, fight or freeze response

25
Q

Sympathetic NS actions

A

Edit

26
Q

Temporal lobe

A
  • mainly responsible for processing auditory info (sensations received from ears)
  • Primary auditory cortex in upper part of temporal lobe
  • performs complex auditory analysis for understanding sound
  • if electronically stimulated will report hearing sounds even if not there
  • directly connected to the hippocampus - vital for encoding info into long term memory
27
Q

Frontal lobe

A
  • largest
  • initiating movement
  • language
  • planning
  • judgement
  • problem solving
  • aspects of personality and emotions
  • left frontal lobe (Broca’s area) responsible for production of speech
  • much of frontal lobe is association area
  • this part is responsible for cognitive processes eg. Attention, planning, problem solving, aspects of personality
  • includes the primary motor cortex in both hemispheres
28
Q

Parietal lobe

A
  • enables a person to perceive their own body and where things are located in their environment
  • location of the primary somatosensory cortex
  • right hemisphere enables person to perceive three-dimensional shapes and designs
  • left hemisphere has a role in reading, writing and performing mental arithmetic
29
Q

Occipital lobe

A
  • entirely concerned with vision
  • ## info from the left of each retina is processed in the left occipital lobe, also true for right
30
Q

Longitudinal fissure

A

Deep grove running from front to rear of cortex

31
Q

Primary visual cortex

32
Q

  • touch, pressure, pain from body , temp
34
Q
