CNS- spinal chord, brain

PNS- autonomic, somatic

Glands and organs.

Unaware

AFFERENT signals: to CNS

EFFERENT signals: from CNS

Efferent:

Sympathetic NS: excites- fight or flight

Parasympathetic NS: inhibits- resting activities

Skin, muscles and joints.

Aware.

AFFERENT signals- to CNS (somosensory)

EFFERENT signals- from CNS (primary motor area)

Rostral- front

Caudal- back

Ventral- bottom

Dorsal- top

Frontal: planning, control impulses, social, attention.

Parietal: spatial perception (from sensory information), sense of touch.

Temporal: language, hearing, object recognition.

Occipital: vision

Sulci: depressions

Sylvian fissure

Central sulcus

Temporal-occipital sulcus

Interhemispheric fissure

Giri: bumps

Pre-central gyrus: efferent, primary motor area

Post-central gyrus: afferent, somatosensory area

Gray: bodies of nerve cells

White: nerve axons

*surface gray matter: cerebral cortex

Subcortical structures: 

-hypothalamus -hyppocampus

Medial structures:

-corpus callosum -thalamus (info from eyes)

-brainstem (signals towards spinal chord)

Redistributes blood in brain if a major supply is blocked.

Anterior cerebral artery (to front of brain)

Posterior cerebral artery

 (to back of brain)

Area between meninges filled with cerebrospinal fluid and connective tissue.

Cushion and absorb shocks
