A and P of Nerves
The part of a neuron that carries impulses toward the cell body. Part that carries it away from cell body.
What is a dendrite? What is an axon? (In that order)
The three layers of the meninges that cover and protect the brain.
What is PAD?
P- Pia mater
A- Arachnoid mater
D- Dura mater
Name 2 functions of the cerebellum.
Controls all body functions related to skeletal muscles, maintains balance, muscle tone, and coordinates muscle movements.
Name the CNS disorder that consists of seizures.
What is epilepsy?
Name the treatment for hydrocephalus
A shunt is placed in ventricle and dumps CSF into abdominal cavity.
Covering that protects axon and speeds up impulse transmission.
What is the myelin sheath?
Name the functions of cerebrospinal fluid.
Acts as a shock absorber, source of nutrients for brain, and gets rid of metabolic waste.
Name the function of the thalamus.
Relays impulses to cerebral cortex.
Name the disorder characterized by the disturbance in voluntary muscle action. Caused by brain damage during birth.
What is cerebral palsy?
Name the CNS disorder characterized by the loss of at least two areas of complex behavior in the brain.
What is dementia?
The periodic gaps in the insulating myelin sheath that allows an impulse to jump across the axon.
What are the nodes of Ranvier?
Name the four lobes of the brain.
What are the frontal, parietal, temporal, and occipital lobes?
Name the function of two of the major lobes.
Frontal- Motor functions, voluntary mov., and speech.
Parietal- Sensory receptors, distance sizes and shapes.
Occipital- eyesight/ vision.
Temporal- Hearing, smell, speech comprehension.
Name the disorder characterized by the inflammation of the meninges.
What is meningitis?
Name the CNS disorder characterized by the progressive degeneration between nerve cells.
What is Alzheimer's?
Name the difference between motor and sensory neurons.
Sensory- Carries impulses toward the spinal cord and brain.
Motor- Carries impulses from brain and spinal cord to muscles and glands.
Name the 3 parts of the brain stem.
What is the midbrain, pons, medulla oblongata.
Identify 5 functions of the hypothalamus.
Regulates sympathetic and parasympathetic
Name the disorder that is characterized by the inflammation of the brain.
What is encephalitis?
Name the area of the brain that contains the cerebral cortex.
What is the cerebrum?
Name the function of the CNS.
Receives messages from the body, brain interprets message, and brain responds to message and carries out activity. Intellect and reasoning.
Name the part of the brain that is composed of the thalamus and hypothalamus.
What is the diencephalon?
Identify a structure and function of the brain stem.
Midbrain- Vision and hearing
Pons- Conducts impulses from cerebrum to cerebellum
Medulla oblongata- Heart rate, rate of respiration, BP, And center for swallowing and vomiting.
Name three characterstics of Parkinson's disease.
Shuffling feet, forward posture, tremors, muscle rigidity, pill-rolling,and decrease of dopamine in neurotransmitters.
Name the CNS disorder characterized by the destruction of the myelin sheath causing delays in nerve impulses.
What is MS?
