The Nervous system - Coggle Diagram
The Nervous system
Aging changes of nervous system
reflexes decrease, thoughts slow down, and nerve cells begin to break down
Some disease of nervous system may occur such as Parkinson's
Breakdown of nerves can affect senses
Reduces sensations
Dementia can occur
autonomic nervous system
supplies the internal organs, including the blood vessels, stomach, intestine, liver, kidneys, bladder, genitals, lungs, pupils, heart, and sweat, salivary, and digestive glands.
regulates certain body processes, such as blood pressure and the rate of breathing. This system works automatically
carries motor information to the visceral organs and glands. It is made up of the sympathetic and parasympathetic autonomic nervous systems.
CNS
Includes Brian and Spinal cord
The brain is made up of three parts
The Cerebellum: In charge of coordination and movement
Brain stem: In charge of all Involuntary functions such as heartbeat, breathing, body regulation
The Cerebrum: all higher Brain functions, in charge of emotions, and everything that makes a person human
The spinal cord: connects brain to the rest of your body
PNS
Includes nerves and ganglia
This connects effector organs
Allows brain and spinal cord to receive and send information
Somatic nervous system
includes all nerves that run to and from the spinal cord and send information to and from the muscles and senses
to connect the central nervous system to the body's muscles to control voluntary movements and reflex arcs
Controls skeletal muscle movement
Sympathetic and parasympathetic divisions
Sympathetic:
body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles.
Parasympathetic: bodily functions when a person is at rest. Some of its activities include stimulating digestion, activating metabolism, and helping the body relax.
