nervous system

• It ochestrates functions to maintain homeostasis 
• The Nervous systm must detect changes in the body like body tempature, sick
• all sensory and motor activites must be directed
• must be directed or intergrated by changes in homeostasis

Central nervous system

• Brain 
• Spinal cord 
• It is the control center of the nervous system 
• Interpreting, intergrating 
• Issuing commands 

Import neurons

• somatic nervous system 
• (autonomic nervous system)
• Sympathetic system 
• parasympathetic system 

Nervous system setup

• Central nervous system 
• (brain )(Spinal cord)
• Peripheral System
• (Sensory neurons "afferent")
• Import neurons efferent

Frontal lobe

• body movement 
• personality 
• speech 

occipital lobe

• interprets vision 
• color light movement 

temporal lobe

• memory 
• understanding langauge 
• hearing 
• sequencing 
• organization 

Parietal lobe

• iterprets words 
• sensory strip 
• visual perception 
• vison hearing motor 

Axial skeleton

• Protects the Brain and spinal cord by using the vertebral colum 
• Ventricles and spinal fluid provide a cushion for protection 
• Body is constantly replenishing.

Cerebellum

Medulla oblongata

• Lies between pons and spinal cord
• It controls key autonomic body functions and it relays nerve signals.
• Important control centers include: respiratory center, cardiac center, vaso

sensory neurons

• Motor neurons 
• Efferent Neurons 
• conducts impulses

• sympathetic nervous system is often called flight or fight
• Parasympathetic system is rest or digest 
• Sympathetic 
• dialtes puppils 
• opens eyelids
