Brain + Spinal Cord

Question 1

Where is Grey/White matter located

Answer 1

Grey: outside layer of brain, inside layer sc
White: inside layer brain, outside layer sc

Question 2

What is the Function of Spinal Cord ?

Answer 2

(Collin of neuron tissue from bottom of brain through the spine)
Function: link between brain + Peripheral nervous system (primary reflex centre)

Question 3

What protects the Spinal Cord ?

Answer 3

Vertebrae (base), cerebrospinal fluid, meanings(soft tissue)

Question 4

What is the brain, what is it protected by?

Answer 4

Control centre for the body.
Protected by skull, cerebrospinal fluid, meninges (soft tissue)

Question 5

What parts consist of the forebrain?

Answer 5

Hypothalamus, cerebrum, thalamus, corpus collusom.

Question 6

What are the 4 lobes and their function?

Answer 6

Frontal Lobe: controls voluntary movement, personality and decision making.
Temporal Lobe: learning, Language comp, memmories
Occipital Lobe: vision processing
Parietal Lobe: touch and temp awareness, pain reception, and spacial awareness.

Question 7

Corpus Collusom (Forebrain)

Answer 7

Consist of white matter. Shares info and connects the left and right hemisphere of the cerebrum. (2 hemispheres)

Question 8

Thalamus (Forebrain)

Answer 8

Relay Centre. Coordinates incoming info between different parts of the brain

Question 9

Hypothalamus (Forebrain)

Answer 9

• link between neurons and endocrine system. Helps keep your body balanced and maintain homeostasis stasis
• controls secretion from pituitary gland

Question 10

Pituitary gland (forebrain)

Answer 10

• gland of the endocrine system, secrets hormones (stores and releases hormones)

Question 11

Cerebellum (Hindbrain)

Answer 11

•muscle coordination, movement & balance

Question 12

Medulla Oblongata (Hindbrain)

Answer 12

•controls breathing, heart rate and blood pressure
• controls autonomic nervous system responses
- sympathetic & parasympathetic

Question 13

Pons (Hind/mid brain)

Answer 13

•links cerebral cortex to cerebellum (relay centre)

Question 14

Brainstem (Midbrain)

Answer 14

• connects cerebrum to spinal cord and cerebellum
-consist of the midbrain, pond and medulla

Question 15

Parasympathetic Response
(Rest & Digest)

Answer 15

Neurotransmitters (Acetylcholine)
Pupils- controlled
Digestion- stimulated
Heart Rate- decreased
Breathing Rate- Decreased
Metabolism- Low; decrease glucose consumption

Question 16

Sympathetic Response
(Fight or Flight)

Answer 16

NeuroTransmitters (Norepinephrine/ Epinephrine)
Pupils- Dilated
Digestion- Inhibited
Heart Rate- Increased
Breathing Rate- Increased
Metabolism- High; increased glucose consumption
