The Nervous System

Question 1

What are the two parts of the nervous system

Answer 1

The central nervous system (brain and spinal cord)

Peripheral nervous system( sensory and motor nerves)

Question 2

Nervous system overview

Answer 2

-Keeps all parts of our body in touch with each other.
-allows us to control muscles by gathering information from inside and outside the body
- the CNS processes the information and interprets it to make a decision on what to do

Question 3

Cerebrum

Answer 3

Speech, memory, skeletal movements

Question 4

Cerebellum

Answer 4

Balance and posture

Question 5

The CNS
What is the spinal cord made up from

Answer 5

Sensory and motor nerves which send info between the body and brain

Question 6

The CNS
What does the Brain do in the CNS

Answer 6

Interprets info, makes decisions and sends the decisions back through the spinal cord to parts of the body

Question 7

The peripheral nervous system
What do sensory neurons do

Answer 7

Collect information from exteroceptors, proprioceptors and interoceptors
They also tell the brain what is happening inside and outside the body

Question 8

Exteroceptor examples

Answer 8

Ears and eyes

Question 9

Proprioceptors examples

Answer 9

Muscles and joints

Question 10

Interoceptor examples

Answer 10

Heart and lungs

Question 11

What do motor neurons do

Answer 11

Take instructions from the brain to the muscles and organs (control muscle action)

Question 12

What are the two parts of the peripheral nervous system

Answer 12

Somatic nervous system- deals with info from our senses like light and sound

Autonomic nervous system- deals with info from our internal organs like lungs and heart

Question 13

What are the two sub systems in the autonomic system

Answer 13

Sympathetic nervous system- fight or flight

Parasympathetic nervous system- calms and relaxes body

Question 14

Information processing in the brain

Answer 14

-when a skill is being learnt they look at the demonstration and listen to instructions which are taking in through the extroroceptors, proprioceptors and the interoceptors
-this is transformed into neural info and sent to the brain. This is known as input
-your brain selects info that you think is importantly and disregards the rest

Question 15

What are the three functions of the brain in performance of skill

Answer 15

1. STSS- the brain selects info that is important and discards other info
2. STM- info is held for up to 20 seconds
3. LTM- makes sense of the info and compared to experiences and devices the best actions to take and transmits decisions to muscles
