Nerves System
Unlike neurons, neuroglia are ________
capable of cell division
Thalamus
the brain's sensory control center, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
pituary gland
the center of control of the endocrine system that secretes a large number of hormones
Dendrite
What is this?
medulla oblongata
contains cardiovascular center
The two cerebral hemispheres are separated by which of the following?
longitudinal fissure
central sulcus
separates frontal and parietal lobes
Pons
sleep and arousal
lateral ventricles
A set of paired ventricles lying within the cerebral hemispheres.
frontal lobe
The lobe at the front of the brain associated with movement, speech, and impulsive behavior.
Hypothalamus
regulating body temperature
Following an accident, J.J. realizes that he is unable to move his left leg. Which area of his brain is most likely affected?
The Right Frontal Lobe
Where are nodes found?
The nodes are found in between the myelin-covered internode.
The cerebellum; the cerebellum adjusts voluntary and involuntary motor activities.
What is this?
multipolar neuron
What type of neuron is this?
Vision; The occipital lobe processes visual information.
Which type of information is processed by the cerebral lobe?
Convergence, which occurs when multiple neurons feed into a single neuron.
Which type of neuronal pool is depicted here and what is its function
Which nucleus or portion of the brain is important in learning and in the storage of long-term memories?
hippocampus
Pia Mater; The pia mater is the innermost meningeal layer and is attached directly to the spinal cord.
what is this?
The brain and spinal cord comprise the
Central Nervous System (CNS)
Which of the following is TRUE regarding the spinal cord?
It forms a continuous connection with the brain
pariental lobe
Lobe located in the upper-back part of your head. Interprets pain, touch, and temperature, as well as some tastes and pressure on the skin
Cerebellum
Maintaining posture
Schwann cells
Oligodendrocytes are to CNS as ________ are to PNS.
Depolarization
Opening of voltage-gated sodium channels in the membrane of a neuron results in
What is the difference between saltatory and continuous propagation of nerve impulses?
Saltatory carries impulses at a faster rate than continuous propagation.
The entire spinal cord is divided into ________ segments.
31
1. Sodium enters the cell. 2. Cell is repolarized. 3. Voltage-gated sodium channels close as voltage-gated potassium channels open. 4. Cell is depolarized. 5. A stimulus arrives. 6. Potassium leaves the cell. 7. Voltage-gated sodium channels open
5,7,1,4,3,6,2
temporal lobe
A region of the cerebral cortex responsible for hearing and language.
A shift of positively charged ions into the cell is called
Depolarization
Which of the following structures is the most superficial?
Dura Mater
What do ependymal cells do?
Ependymal cells line the central canal and ventricles of the brain and produce cerebrospinal fluid (CSF).
Medulla
an extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration
Which of the following is an automatic processing center that controls balance and programing and the fine-tuning of learned movements?
cerebellum
which of the following parts of the brain is not matched correctly with its function?
cerebrum: adjusting blood pressure
cerebal cortex
outside of cerebum that controls highest functions like reasoning, memory, conciousness, speech, voluntary mucles movement, vision, hearing, sensation, etc - part of brain therefore part of central nervous system
The arrival of an action potential at the end of an axon results in the
release of a neurotransmitter from the axon terminal
