Neurons
The three parts that neurons are composed of:
What are the cell body, axon and dendrite?
What skeletal structure surrounds the thick column of nerves, known as the spinal cord?
The vertebrae
What does the central nervous system consist of
What is the brain and spinal cord?
serves as "station" for information passing between spinal cord and the cerebrum or between the cerebrum and cerebellum.
What is the midbrain?
The lobe that is responsible for speech production, concentration, problem solving, planning, and voluntary muscle control
What is frontal lobe?
A long extension that transmits signals away from the cell body
What is axon?
What connects the spinal cord to the brain?
The brain stem
Cranial nerves which extend from the brain, spinal nerves which stem from the spinal cord, sensory fibers which are all over the body and send impulses to the CNS via the cranial nerves and spinal nerves.
What does the peripheral nervous system consist of?
This extends from the midbrain to the medulla oblongata. Plays an important role in the regulation of breathing rate and rhythm.
What is pons?
Responsible for general interpretation, understanding speech, ability to use words, sensations felt on the skin: heat/cold, pressure, touch, pain, and other sensations.
What is the parietal lobe?
Branched process that extends outward from the cell body.
What is the dendrite?
What system gets the information to the spinal cord?
Peripheral Nervous System
How many main parts are there in a neuron?
What is 3?
Connects the spinal cord with the pons. Acts as a relay for sensory and motor information. Control the heart rate, blood pressure, and respirations.
What is medulla oblongata?
Responsible for remembering visually, interpretations of sensations, remembering through sounds, hearing, and learning.
What is the temporal lobe?
In the PNS, this occurs when a Schwann cell wraps its membrane around an axon.
What is myelination?
What surrounds the spinal cord?
CSF (Cerebrospinal fluid)
What does an axon terminal hold inside small vessicles?
neurotransmitters
Made up of the hypothalamus and thalamus and is located in the walls and floor of the ventricle.
What is the diencephalon?
lobe responsible for recognizing objects visually, vision, combining images received visually.
What is the occipital lobe?
They form myelin in the CNS.
What is oligodendrocytes?
Can the spinal cord be considered the head quarters of the central nervous system?
Name the gaps between the myelin sheaths on the axon?
nodes of ranvier
Regulates sleep, hunger, thirst, body temperature, and maintains homeostasis.
What is the hypothalamus?
Lies just below the cerebrum; a fissure divides this lobe into 2 parts; coordinates your muscle movements; maintains normal muscle tone
What is the cerebellum?
