Nervous System Ll

Front 1

Pia

Back 1

Bound firmly to underlying neuronal tissue and carried blood supply for brain and spine. It is the most delicate

Front 2

Frontal lobe

Back 2

MOTOR cortex, carries out motor mvmts.
Reasoning, voluntary motor function . Higher level cognitive functions and language
The more fine the mvmt, the more cell bodies needed !

Front 3

Parietal lobe

Back 3

SOMATOSENSORY cortex.
Receives/processes tactile sensory info like pain pressure touch temperature.

Front 4

Temporal lobe

Back 4

Primary auditory cortex, interprets sound and language
Important in memory function

Front 5

Occipital lobe

Back 5

Primary visual cortex. Interprets visual stimuli (from retinas)

Front 6

Forebrain

Back 6

Telencephalon( cerebrum, cerebral cortex, basal ganglia, lambic system) and diencephalon ( thalamus and hypothalamus)

Front 7

Cerebrum

Back 7

Largest and highly developed. L and R hemispheres connected by corpus callosum. Controls higher functions

Front 8

Cerebral cortex

Back 8

(Discussed later)

Front 9

Basal ganglia

Back 9

Controls cognition, mvmt coordination, and voluntary mvmt.

Front 10

Amygdala

Back 10

Deep w/in temp lobe.arousal, autonomic responses about fear, emotional responses and memory

Front 11

Hippocampus

Back 11

Keeps new memories, emotional responses, special orientation.

Front 12

Thalamus

Back 12

Body's relay center for all sensory info. Associates sensation with emotion. Plays a part in arousal and/or alerting mechanism

Front 13

Hypothalamus

Back 13

Controls autonomic functions, energy levels, wakefulness, hunger , hormones, mood and behaviour functions, metabolism ( I.e homeostasis)

Front 14

Midbrain

Back 14

Tectum and tegmentum

Front 15

Tectum*

Back 15

At dorsal part of midbrain, superior coniculli (visual receptors) and inferior coniculli (auditory receptors). Controls auditory and visual responses.
