Nervous System (updated)

QuestionAnswer
The nervous system enables the body to respond and adapt to changes that occur both inside and outside the body.
A space between the axon of one neuron and the dendrites of other neurons is called a synapse
Associative or internuncial nerves carry sensory and motor messages.
What is responsible for reflex actions including chewing, tasting, and saliva production The pons
The spinal cord ends at the fourth or fifth lumbar vertebra.
Spinal nerves are mixed nerves called afferent and efferent
What brain damage leads to a disturbance in voluntary muscle action Cerebral palsy
A cerebrovascular accident can be caused by a/an obstruction of blood flow to the brain or a hemorrhage.
What drug treatment during the first three hours after a cerebrovascular accident can help prevent brain damage. thrombolytic drugs
Paralysis of the arms, legs, and body below the spinal cord injury is called. Quadriplegia
What disease includes tremors, stiffness, muscular rigidity, a shuffling gait, and loss of facial expression. Parkinson’s disease
Nerve pain caused by inflammation, pressure, toxins, and other diseases is called Neuralgia
Drugs that help prevent injury to neurons is called Neuroprotective agents
The basic structural unit of the nervous system is the neuron
A nerve fiber that carries impulses toward the cell body is a/an dendrite
A condition caused by continuous repetitive movement of the wrist is called carpal tunnel syndrome
Sensory nerves that carry messages from all parts of the body to the brain and spinal cord are afferent
The part of the brain responsible for muscle coordination, balance and posture, and muscle tone is the cerebellum
The part of the brain responsible for conducting impulses between brain parts and for certain eye and auditory reflexes is the midbrain
The part of the brain that regulates heartbeat, respiration, swallowing, coughing, and blood pressure is the medulla oblongata
The part of the brain that is responsible for thought, reasoning, memory, speech, and voluntary body movement is the cerebrum
The membranes covering the brain and spinal cord are the meninges
Cerebrospinal fluid is produced by special structures called choroid plexuses
Hollow spaces in the brain filled with cerebrospinal fluid are called ventricles
The division of the autonomic nervous system that acts in times of emergency is the sympathetic
The thick, tough outer covering of the brain and spinal cord is the dura mater
The sympathetic and parasympathetic nervous systems work together to maintain a balanced state called homeostasis
Paralysis of the lower extremities is called paraplegia
An excessive accumulation of cerebrospinal fluid in the ventricles of the brain is called hydrocephalus
A cerebrovascular accident commonly causes hemiplegia
Abnormal electrical impulses in the neurons of the brain cause epilepsy
An acute inflammation of nerve cells caused by the herpes virus is called shingles
A chronic, progressive, disabling condition resulting from a degeneration of the myelin sheath is called multiple sclerosis
An inflammation of the brain frequently caused by a virus contracted from a mosquito bite is called encephalitis
What are two main divisions of the nervous system? central nervous system, peripheral nervous system
What are the two divisions of the autonomic nervous system? sympathetic, parasympathetic
What are functions of the cerebrospinal fluid shock absorber, carries nutrients, removes metabolic products and wastes
What are functions of the body regulated and controlled by the hypothalamus autonomic nervous system, temperature, appetite, water balance, sleep, blood vessel constriction and dilation
What center is responsible for reasoning, thought, memory, speech, sensation, sight, smell, hearing, and voluntary body movement cerebrum
What area is responsible for muscle coordination, balance and posture, and muscle tone; cerebellum
What area in the brain contains the thalamus and hypothalamus diencephalon
What part of the brain acts as the relay center to direct sensory impulses to the cerebrum thalamus
What area of the brain regulates and controls the autonomic nervous system, temperature, appetite, water balance, sleep, blood vessel constriction and dilation hypothalamus
What area of the brain conducts impulses between brain parts and responsible for certain eye and auditory reflexes; midbrain
What area of the brain conducts messages to other brain parts and controls reflex actions such as chewing, tasting, and saliva production pons
What area of the brain regulates heartbeat, respiration, swallowing, coughing, and blood pressure medulla oblongata
What are the three meninges dura mater, arachnoid membrane, pia mater
A neurological disorder tht causes a client to make sounds and twitch uncontrollably is called Tourette's syndrome
A progressive degeneration of neurons in the brain is called Alzheimer's
A defect in the spinal column in which the spinal cord and/or its covering protrude outside the vertebrae is called Spina bifida
What consists of a cell body containing a nucleus, nerve fibers called dendrites and a single nerve fiber called an axon Neuron
A combination of many nerve fivers located outside the brain and spinal cord is called Nerves
Contains four lobes, the frontal, parietal, temporal and occipital. Cerebrum
Acts as a relay center and directs sensory impulses to the cerebrum. Thalamus
The spinal cord ends at the first or second lumbar vertebra
The innermost membrane covering the brain and spinal cord is called the meninges
After circulating, cerebrospinal fluid is absorbed into the blood vessels through special structures called arachnoid villi
What nervous system consists of 31 pairs of spinal nerves and 12 pairs of cranial nerves somatic
What nervous system increases heart rate, increases respiration, and slows activity in the digestive tract. sympathetic nervous
What type of seizures are milder and characterized by a loss of consciousness lasting several seconds. petit mal seizures
Meningitis is treated with antibiotics, anticonvulsants, and/or medications for pain and cerebral edema.
Paralysis in the lower extremities or lower part of the body and is caused by a spinal cord injury is called paraplegia
Two main divisions of the nervous system is central nervous system and peripheral nervous system
Two divisions of the autonomic nervous system are called sympathetic, parasympathetic
Functions of the cerebrospinal fluid is shock absorber, carries nutrients, removes metabolic products and wastes
Autonomic nervous system, temperature, appetite, water balance, sleep, blood vessel constriction and dilation is called functions of the body regulated and controlled by the hypothalamus.
Center for reasoning, thought, memory, speech, sensation, sight, smell, hearing, and voluntary body movement: cerebrum
Responsible for muscle coordination, balance and posture, and muscle tone; cerebellum
Contains the thalamus and hypothalamus: diencephalon
Relay center to direct sensory impulses to the cerebrum: thalamus
Regulates and controls the autonomic nervous system, temperature, appetite, water balance, sleep, blood vessel constriction and dilation hypothalamus
Conducts impulses between brain parts and responsible for certain eye and auditory reflexes midbrain
Conducts messages to other brain parts and controls reflex actions such as chewing, tasting, and saliva production pons
Regulates heart beat, respiration, swallowing, coughing, and blood pressure medulla oblongata
Dura mater, arachnoid membrane and pia mater three meninges.
What do neurons contain that carry messages to the cell body dendrites
Nerves are a combination of many nerve fibers located outside brain and spinal cord
