CNS includes
Brain, spinal cord
Nervous system is organized into two main subdivision
Central nervous system (CNS) and Peripheral nervous system (PNS)
PNS includes
All nervous tissue outside the CNS
Components of PNS
Nerves, ganglia, enteric plexuses and sensory receptors.
Three systems of the PNS
Somatic nervous system (SNS), autonomic nervous system (ANS) and enteric nervous system (ENS)
Somatic nervous system sensory neurons contain
Head, body wall, limbs, vision, hearing, taste, smell.
Somatic nervous system motor neurons contain
Skeletal muscles
What type of control is the somatic nervous system
Voluntary
Where is Autonomic nervous system sensory neurons
Autonomic sensory receptors and neurons
Autonomic nervous system motor neurons
Smooth muscles, cardiac muscles, glands
What control is the autonomic nervous system
Involuntary
Where is Enteric nervous system sensory neurons
Enteric sensory receptors and neurons
Enteric nervous system motor neurons
Smooth muscles, glands, endocrine cells of GI tract
What control is enteric nervous system
Involuntary
What can consciously control skeletal muscles
Somatic nervous system
