NERVOUS SYSTEM Flashcards
It coordinates and regulates the body’s feedback mechanism to maintain homeostasis.
Nervous System
Cerebrum (largest section)
Cerebellum (located below the cerebrum)
Diencephalon (controls emotions)
Midbrain (eye and auditory reflexes)
Pons (reflex actions)
Medulla Oblongata (regulates heart and blood vessels function)
The Brain
Cervical
Thoracic
Lumbar
Spinal Nevers
Afferent (Carries Information from the body to the brain)
Effect (Carries Information from the brain to the body)
Spinal Cord
Two main Parts of the CNS
Brain and Spinal Cord
It feeds information into your brain from most of your senses. It carries signals that allow you to move your muscles
Peripheral Nervous System
Two main parts of the PNS are the;
Somatic Nervous System (voluntary control of the body movements)
Autonomic Nervous System (Involuntary control of the body movements)
It is the Flight and Fight response
carries signals that put your body’s systems on alert
Sympathetic Nervous System
It regulates “rest and digest” functions.
carries signals that relax those systems after being alerted
Parasympathetic nervous system
is the basic unit of the nervous system and it is called a
Neuron / Nerve Cell
The cell body of a neuron has
the nucleus, dendrites and axons.
The gap between neurons
Synapse
It occurs to INCREASE the change, example: childbirth, blood clotting
Positive Feedback
DECREASES the changes, example: when you have fever you are perspiring, our body regulates the temp)
Negative Feedback
This is a 28 cycle when a female has started to develop
Mensturation
They work together to detect external and internal signals, transmit and integrate information, and maintain homeostasis. They do all of this by producing appropriate responses to internal and external cues and stressors.
Nervous and Endocrine system
