Central Nervous System Notes
Central Nervous System (CNS):
“control center” of the body; consists of brain and spinal cord.
Brain: controls most functions of the body
Spinal Cord: links brain to Peripheral Nervous System
Actual Human Central Nervous System
Central Nervous System NotesBrain: consists of three (3) parts:
Cerebrum: processes sensory information, mental processes (thought: learning, remembering, judgement; conciousness); largest part of brain. Left Half: Math, Science (analytical) Right Half: Music, Art, (creativity)Cerebellum: muscle coordination & balanceBrain Stem: primitive/basic involuntary activities (breathing, heartbeat, blinking eyes)
Central Nervous System Notes
Peripheral Nervous System NotesPeripheral Nervous System (PNS): consists
of all nerves outside of the Central Nervous System. Subdivided into the Somatic & Autonomic Nervous System.
Somatic Nervous System: controls voluntary actions (ex: taking notes, writing)
Autonomic Nervous System: controls involuntary actions; reflex actions (ex: blinking, breathing)
Peripheral Nervous System NotesReflex Action: autonomic response that occurs very rapidly and without concious control; helps to protect the body; muscle and spinal cord involvement but not the brain (see transparancy).
Nervous System Damage: Concussions and Spinal Cord injuries.
Concussion: bruise of the brain when brain collides against skull.
Spinal Cord injury: cut or crushed, resulting in paralysis (loss of movement) or death.
