Neurons |
Perform communication, information processing, and control functions of the nervous system. |
|
|
Neutroglia (glial cells) |
They separate and the neurons, provide a supportive framework for neural tissue, act as a phagocytes, and help regulate the composition of the interstitial fluid. |
|
|
Central nervous system (CNS) |
Brain and spinal cord. Functions: Integrate Processing Coordinating sensory data and motor commands. |
|
|
Peripheral nervous system (PNS) |
Delivers sensory information to the CNS and carries motor commands to peripheral tissues and systems. |
|
|
Cranial nerves |
Nerves connected to the brain. |
|
|
Spinal nerves |
Nerves attached to the spinal cord. |
|
|
Afferent division |
Brings sensory information to the CNS from receptors in peripheral tissues and organs. |
|
|
Receptors |
Sensory structures that either detect changes in the environment or respond to specific stimuli. |
|
|
Efferent division |
PNS carries motor commands from the CNS to muscles, glands and adipose tissue. |
|
|
Effectors |
These target organs which respond by doing something. |
|
|
Somatic nervous system (SNS) |
Controls skeletal muscle contractions. Voluntary: under conscious control. Driving water. Involuntary: subconscious level. Placing hand in hot stove. |
|
|
Autonomic nervous system (ANS) Visceral motor system |
