Nervous System Pt.1

The three functions of the NS

• Sensory, Integrative, motor

• Brain, Spinal, Fluid

• Spinal, integrative, motor

• Motor, Sensory, autonomic

Sensory functions

Multiple answer question

• creates sensation's, memory, thoughts, decisions

• Impulse carried to effectors

• Sensory receptors gather information

• Information is carried to the CNS

Integrative Function

• carries information

• Creates sensations, memory, thoughts, decisions

• acts out decisions

• carries impulses

Motor Function

• Acts out decisions

• creates sensations

• information from the CNS

• comes from impulse that's carried to the effectors

Central nervous system

• Brain

• Nasal

• Spinal

• cardiovascular

Peripheral Nervous system

• Cranial nerves

• Cranial nerves outside the brain

• Spinal nerves outside the spinal cord

• Cardiovascular nerves outside the heart

Sensory Afferent Division

• Motor neurons

• Connects skin, limbs, and visceral (organs) to CNS

• Specialized nerve endings

• Responds to stimuli: pain, pressure, temperature

Motor efferent Division

• Conducts impulses form the CNS to its effectors

• responds to stimuli

• Fight or flight

• Parasympathetic

Motor

Somatic Nervous system

• Voluntary

• Involuntary

• conducts impulse from CNS to skeletal muscles

• conducts impulse form skeletal muscles to CNS

Autonomic Nervous System

• Involuntary

• Conducts impulse CNS to cardiac muscles

• voluntary

• Smooth muscle and glands (visceral organs)
