Biology 12 Brain Parts/function

Front 1

Corpus Callosum

Back 1

bundle of axons that interconnects two hemispheres and allows impulses to pass between

Front 2

Thalamus

Back 2

Controls sensory and motor functions. Almost all sensory information enters here before reaches the cerebral cortex.Sorting Center. Relaying of incoming impulses

Front 3

Hypothalamus

Back 3

Involved in homeostasis, emotion, thirst, hunger, circadian rhythm and control of ANS. monitoring body. Affects changes to maintain homeostasis

Front 4

Pons

Back 4

Screens out unnecessary impulses

Front 5

Medulla Oblongata

Back 5

Maintain vital body functions like breathing and heart rate

Front 6

Cerebellum

Back 6

Associated with regulation and coordination of movement, posture, and balance. controls muscle coordination and balance

Front 7

Cerebrum

Back 7

Associated with higher brain functions like thought and action. centre for integrated though. Relays messages.

Front 8

Anterior Pituitary

Back 8

produces and secrets its own hormones.

Front 9

Posterior Pituitary

Back 9

stores and secrets hormones made in the hypothalamus

Front 10

Frontal Lobe

Back 10

integrated thought. Initiates motor responses

Front 11

Parietal Lobe

Back 11

sensory portion

Front 12

occipital lobe

Back 12

visual association

Front 13

temporal lobe

Back 13

hearing

Front 14

Spinal Cord

Back 14

sends nerves to all parts of the body. Sends impulses/nerves/messagse to brain to be sent out to body.
