Brain And NS 3

Question 1

Components of the invertebrate brain

Answer 1

Brain stem, cerebellum, cerebrum

Question 2

Shark brain

Answer 2

Very simple, deals with autonomic function, sensory input, and motor response, little to no cerebellum/cerebrum

Question 3

Alligator brain

Answer 3

More developed brain stem, olfactory bulb, and cerebellum, motor responses can be complex, little to no cerebrum

Question 4

Bird brain

Answer 4

Displays personality and memory, highly developed sense of smell, precise and coordinated motor/sensory systems

Question 5

Human brain

Answer 5

Complex behaviour, socially aware, conscious, cerebrum is most prominent area, capable of advanced learning and memory, complex personality

Question 6

Neural tube

Answer 6

Hollow tube of tissue that runs the length of the early embryo on the dorsal surface

Question 7

Hindbrain components

Answer 7

Cerebellum and pons & medulla (brain stem)

Question 8

Cerebellum

Answer 8

Intricate control of motor and sensory function

Question 9

Brain stem

Answer 9

Connects spinal cord and brain, controls involuntary functions

Question 10

Midbrain

Answer 10

Also part of the brain stem, associated with sensory inputs like vision and olfaction

Question 11

Forebrain components

Answer 11

Telencephalon and diencephalon

Question 12

Telencephalon (cerebrum)

Answer 12

Divided into two hemispheres, complex array of lobes, in charge of perception, learning, memory, and conscious behaviour

Question 13

Diencephalon

Answer 13

Insists of thalamus and hypothalamus

Question 14

Grey matter

Answer 14

Forms layer over brain surface, highly convoluted, made up of gyri (ridges) and sulci (valleys)

Question 15

Relight hemisphere associations

Answer 15

Sensory and motor function on the left side of the body

Question 16

Left hemisphere associations

Answer 16

Sensory and motor function on the right side of the body
