Lab #5 Flashcards
Also known as neurologic function or intracranial regulation
Brain function
Brain function is dependent upon
Oxygenated blood
Voluntary and autonomic responses are controlled by
The nervous system
Is composed of the central nervous system, the peripheral nervous system, and the autonomic nervous system
Nervous system
Make up the central nervous system
The brain and its protective structures
Circulates around the brain and spinal cord to provide a cushion, maintain intracranial pressure, provide nutrition, and remove metabolic waste
The cerebrospinal fluid
The brain consists of
Cerebrum, diencephalon, cerebellum, and brainstem
The largest part of the brain and contains four lobes
Cerebrum
Responsible for voluntary motor activity
Frontal lobe
Receives sensory input
Parietal lobe
Contains the auditory cortex
Temporal lobe
Contains the visual cortex
Occipital lobe
The diencephalon is made up of
Thalamus, hypothalamus, epithalamus, and subthalamus
This maintains homeostasis
Hypothalamus
The portion of the brain that is responsible for smooth, coordinated voluntary movement
Basal ganglion
Made up of the midbrain, pons, and medulla oblongata (involuntary functions)
Brainstem
The portion of the brain that controls coordinating movement, balance, muscle tone, and proprioception
Cerebellum
A complex tract that carries sensory information between the body and the brain
Spinal cord
Consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves
Peripheral nervous system
Components of the autonomic nervous system
The sympathetic nervous system and the parasympathetic nervous system
Controls the internal environment of the body
Autonomic nervous system
Progressive demyelination of nerve fibers of the brain and spinal cord
Multiple sclerosis
