Brain - Homeostasis

Question 1

Matters - Grey

Answer 1

Outside, composed of myelinated axons

Question 2

Matter - White

Answer 2

Inside, Interneurons, which lack myelin, connecting one thing to another

Question 3

Cerebrum

Answer 3

• All conscious action
• Largest part of brain (80%)
• Conscious thought, sensory perception
  -Behaviors, emotion, learning and memory
• Outer grey layer is cerebral cortex
  -The cerebrum is divided into a left and right hemisphere by a longitudinal fissure
  Branch like white and grey matter

Question 4

Left hemisphere of brain

Answer 4

Controls right side of body, logic, maths, and language

Question 5

Right hemisphere

Answer 5

Controls left side of body
Creativity, art and music

Question 6

Surface of cerebrum (cerebral cortex)

Answer 6

Thinking and problem solving

Question 7

Cerebellum

Answer 7

Movement, coordination, balance, fire motor skills, and posture
Under cerebrum at the back of the brain
Run and play sports smoothly
Helps us move through coordinating muscle activity

Question 8

Hypothalamus

Answer 8

Body’s control coordination centre
Stable state responsible (homeostasis, set point)
Body temp, water balance and hunger

Question 9

brain stem

Answer 9

Midbrain, pons, medulla and oblongata
Heartbeat, blood vessels, breathing, salivation, and swallowing
Work on own
With spinal cord it controls involuntary actions, subconscious, automatic
Arrangement of grey and white matter is just white - no branches like the cerebrum

Question 10

Corpus Callosum

Answer 10

Connects information between left and right side of the brain
A large band of nerve fibres connecting the two brain hemispheres and carries messages between them
Underneath cerebrum (do diagram)

Question 11

Pituratry gland

Answer 11

Master gland
Controls others
has main role in water balance and growth + reproduction

Question 12

Hippocampus

Answer 12

Primarily responsible for converting short-term memories into long-term memories, also playing a role in spatial memory and navigation.
Emotions , memory and automatic functions

Question 13

Folds on brain

Answer 13

Large amounts of information to be processed through nerve cells

Question 14

How many neurons

Answer 14

over 86 billion

Question 15

How does the brain connect with the rest of the body

Answer 15

Spinal cord through CNS and PNS
Electrical and chemical signals through neurons

Question 16

MEMORY AND LEARNING

Answer 16

CEREBRUM
