Differentiate Divisions Of Nervous System (Pt 1):
Three Main Functions:
1) Monitors the body's internal & external environment
2) Integrates sensory information
3) Coordinates voluntary & involuntary responses
Differentiate Divisions Of Nervous System (Pt 2)
Central Nervous System (CNS)
- Includes the brain & spinal cord
- Integrates & coordinates sensory processing and motor transmission
- Location of higher functions like intelligence, memory & emotion
Peripheral Nervous System
- All neural tissue outside the Central Nervous System
- Communication connection between the Central Nervous System & the rest of the body
Peripheral Nervous System Functional Divisions:
>Afferent Division - Sensory
- Brings information to the Central Nervous System from receptors in the body tissues and organs.
- Receptors - sensory structures that detect changes in the environment or respond to specific stimuli
>Efferent Division - Motor
- Carries information away from the Central Nervous System to muscles and glands. These organs and tissues are called effectors.
>Efferent Division Subdivisions
- Somatic Nervous System
- Control skeletal muscle contractions
- Voluntary Contractions - under conscious control (lifting glass of water to lips)
- Involuntary Contractions - Simple or complex movements controlled at the subconscious level. (placing hand on hot stove and pulling back immediately) this is also known as reflex |
