Nervous system Flashcards
Major control system of homeostasis and the “main processing center”
provides monitoring, response and regulation of all systems in the human body.
Nervous system
Serves as the main processing center for the entire nervous system.
Central Nervous System (CNS)
➤ Connects the central nervous system to the organs and limbs
Peripheral Nervous System (PNS) ➤
This is an organ located within the skull that functions as organizers and distributor of information for the body.
Brain
- large, upper part of the brain that controls activity and thought.
Cerebrum
the part under the cerebrum that controls postures, balance, and coordination.
Cerebellum
part that connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate, and blood pressure.
Brain stem
This serves as a channel for signals between the brains and the rest of the body, and controls simple musculoskeletal reflexes without input from the brain.
Spinal Cord
the nerves that carry motor and sensory signals between the spinal cord and the body.
Spinal Nerves
Peripheral Nervous System
- This system is associated with the voluntary control of body movements
a. Somatic Nervous System
the nerve fibers that carry information into and out of the brain stem.
Cranial Nerves
This system is associated with the involuntary control of body movements.
Autonomic Nervous System
it is activated when the body is an dynamic role or stress. (e.g., increase heart rate, and breathing, dilation of pupil, sweating, etc.)
Sympathetic
- it maintains body functions and restores the body to normal or relaxed mode.
Parasympathetic
