(28 cards)
3 Parts of the Nervous System
Autonomic, Peripheral, Central
2 Parts of the Autonomic Nervous System
Parasympathetic, Sympathetic
4 Parts of Peripheral Nervous System
Cranial nerves, brachial plexus, spinal nerves, lumbosacral plexus
Two parts of Central Nervous System
Brain & Spinal Cord
Dendrites…?
Receive impulses from other parts of the nervous system and bring them toward the body
Axons…?
Transmit impulses away from the cell body
What surrounds axons?
Myelin
Function of myelin?
(Increase the speed of impulse conduction in the myelinated fiber (white matter)
Gray matter is?
Areas that contain unmyelinated fibers
A nerve fiber is…?
The conductor of impulses from the neuron
Transmission of impulses from one neuron to another occurs at a ______.
Synapse
A group of myelinated nerve fibers within the CNS that carries a specific type of information from one area to another is called what?
Tract
Two major types of nerve fibers in peripheral nerves?
Motor and Sensory
Efferent =
Motor
Afferent =
Sensory
The brain is made up of these 3 things…
Cerebrum, brainstem, cerebellum
The largest portion of the brain is…
The cerebrum
Which lobe controls personality, motor movement, and expressive speech?
Frontal Lobe
Which lobe is responsible for vision and recognition of size, shape, and color?
Occipital Lobe
Which lobe controls gross sensation (touch and pressure), fine sensation (determination of texture, weight, size, and shape)?
Parietal Lobe
Which lobe is considered the center of behavior, hearing, language reception, and understanding?
Temporal
The _______ is a mass nerve cells, which serves as a relay station for body sensations, where pain is perceived?
Thalamus
The _____ is important for hormone function and behavior (also known as basal ganglia) and is also important for coordination of motor movement.
Hypothalamus
“Little Brain” refers to the
Cerebellum
