brain stuff

Question 1

Walnut shaped; behind cerebrum
“Little brain” 
Unconscious coordination of posture, reflexes, body movements
Fine voluntary motor skills
Receives info from proprioceptors

Answer 1

cerebellum (hindbrain)

Question 2

Base of brain-stem
Connects brain to spinal cord
Coordinates reflexes and homeostasis maintenance functions like HR, vasoconstriction/dilation, breathing, swallowing rates

Answer 2

medulla oblongata (hindbrain)

Question 3

Above and in front of medulla oblongata

Relay centre

Answer 3

pons (hindbrain)

Question 4

runs coordination and homeostasis

Answer 4

hindbrain

Question 5

Above pons
Processes info from sensory neurons in eyes, ears and nose (so: senses)
Important role in eye movement and control of skeletal muscles
Relays visual and auditory info b/w hind and forebrain

Answer 5

midbrain

Question 6

Base of forebrain
Consists of neurons connection hind and forebrain
Also between areas of sensory system except smell
“Relay station” of brain

Answer 6

thalamus

Question 7

Below thalamus
Regulates body’s internal environment
Controls actions of pituitary gland
Controls BP, HR and temperature, plus basic drives (ex. thirst/hunger); emotion

Answer 7

hypothalamus

Question 8

Largest part of brain
Divided into L and R hemispheres
Contains centres for intellect, learning, memory, consciousness, language
Interprets/controls response to sensory info

Answer 8

cerebrum

Question 9

Receive and analyze visual info
Needed for recognition of what is being seen
Damage can result in ability to see objects but not recognize what they are

Answer 9

occipital lobes

Question 10

Main function is auditory reception

Linked to understanding speech and retrieving visual/verbal memories

Answer 10

temporal lobes

Question 11

Receive and process sensory info from skin

Proportion (size) of different areas is relative to importance of sensory info for that body part

Answer 11

parietal lobes

Question 12

Integrates info from other parts of brain

Controls reasoning, critical thinking, language use and personality

Answer 12

frontal lobes

Question 13

Series of 3 membranes

Surround and protect CNS

Answer 13

meninges

Question 14

Series of nerve fibres

Connect L and R hemispheres of brain

Answer 14

corpus callosum

Question 15

Dense, clear liquid derived from blood plasma, found in ventricles of brain, central canal of spinal cord and between meninges
Transports hormones, WBC, nutrients across blood-brain barrier to cells of brain and spinal cord
Shock absorber to cushion brain

Answer 15

cerebrospinal fluid (CSF)
