Nervous System 1
What are the four parts of the neuron?
dendrites, cell body, axon, and myelin sheath
What kind of messages travel from the body up to the brain?
Sensory (Afferent)
The membranes that cover and protect the brain and spinal cord are known as the:
Meninges
The message that travels from the brain to the nerves of the muscles and glands are called:
Motor (efferent)
Special chemicals located at the end of each axon which allow the nerve impulse to pass from one neuron to another.
Neurotransmitters
What is the section of the brain responsible for muscle coordination, balance, posture, and muscle tone?
Cerebellum
After an emergency, this system counteracts the actions of the sympathetic system by slowing the heart rate, decreasing respirations, and lowering blood pressure.
Parasympathetic nervous system
In times of emergency this system prepares the body to act by increasing heart rate, respirations, and blood pressure.
Sympathetic nervous system
What is a balanced state in the body called?
Homeostasis
Also know as Lou Gehrig's disease, a chronic, degenerative neuromuscular disease.
Amyotrophic Lateral Sclerosis
What is the lowest part of the brain stem which connects with the spinal cord and is responsible for regulating heartbeat, respirations, swallowing, and blood pressure?
Medulla oblongata
The axon of one neuron lies close to the dendrites of many other neurons. What are the gaps between them known as?
Synapses
What are the three membranes of the meninges called?
Dura mater, arachnoid membrane, pia mater
This division of the peripheral nervous system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves.
Somatic nervous system
A disturbance in voluntary muscle action which is caused by brain damage, lack of oxygen to the brain, birth injuries, prenatal rubella and infections.
Cerebral Palsy
What is the basic structural unit of the nervous system?
Neuron
The lobes of the cerebrum include:
Frontal, parietal, temporal, and occipital
The ventricles are filled with a clear colorless fluid known as:
Cerebrospinal fluid
This section of the brain is located below the midbrain and in the brainstem and is responsible for conducting messages to other parts of the brain and certain reflexes:
Pons
Also known as a stroke, occurs when blood flow to the brain is impaired, resulting in a lack of oxygen and destruction of brain tissue.
Cerebrovascular accident CVA
What are the hollow spaces that connect with each other and with the subarachnoid space in the brain called?
Ventricles
What is the largest and highest section of the brain responsible for reasoning, thought, and judgement known as?
Cerebrum
What are the two divisions of the autonomic nervous system called?
Sympathetic nervous system and parasympathetic nervous system
The two main divisions of the nervous system are:
Central nervous system and peripheral nervous system
Inflammation of the brain.
Encephalitis
