hypothalamus
Intergrates sensory information and sends it to appropriate areas of the cerebrum.
thalamus
Responsible for thought processes associated with learning, memory, speech, and language.
cerebrum
Maintains posture, balance and coordination.
cerebellum
Regulates heartbeat, breathing, blood pressure, and reflexes such as coughing, sneezing and hiccuping.
medulla oblongta
Center for strong emotional responses such as fear and pleasure.
limbic system
Which of the following is NOT true of the spinal cord?
Due to the communication of the ascending and descending tracts with the brain, damage to the right side of the brain will affect functions on the right side of the body.
Which of the following is NOT true of the function of neurotransmittors?
They are released continuously by presynaptic neurons.
The words are seen on the page.
visual cortex of the occipital lobe
Meaning of words are interpreted.
Wernicke's area
Verbal response is generated.
Broca's area

Primary motor area of frontal lobe
Portion of neuron containing the nucleus and most other cell organelles.
cell body
Conducts nerve impulses from cell body to other neurons.
axon
Conducts nerve impulses from other neurons to the cell body.
dendrite
Type of neuron that carries carries messages from a sensory receptor (i.e. taste buds) to the CNS.
sensory
Type of neuron that relays messages between neurons within the CNS.
interneuron
Type of neuron that carries messages from the CNS to an effector (i.e. muscle fiber).
motor
Region of close proximity between neurons.
synapse
Chemicals which relay nerve messages across a synaptic cleft.
nerotransmitters
According to the MOST RECENT brain hemisphere research:
Both the right and left hemispheres process the same information but in different ways.
A woman is a sound sleeper, sleeping soundly while her husband watches TV in bed and later as he snores loudly beside her. However she quickly awakens at the first cry of her newborn in the next room. This "selective" awakening response is due to the activity of the:
reticular formation
Which of the following is a correct description of common eye abnormalities?
Astigmatism results from an uneven cornea causing the rays to focus unevenly.
Stimulated by changes in temperature.
thermoreceptors
Respond to light energy such as the rod cells of the eyes.
photoreceptors
Type of receptor responsible for taste, smell and the monitoring of blood pH in certain arteries.
chemoreceptors
Naked dendrites that respond to chemicals released by damaged tissues.
pain receptors
Stimulated by changes in pressure such as air borne sound waves, changes in gravity and motion, and the sense of touch.
mechanoreceptors
Detect changes in blood pressure in certain arteries.
pressoreceptors
Respond to stretching of muscle fibers, tendons, joints, and ligaments allowing us to be aware of body position.
proprioceptors
Contains sensory receptors for sight.
retina
Refracts and focuses light rays.
lens
Admits light.
pupil
Controls the shape of the lens to aid in focusing.
cilary body
The _________ permit vision in dim light at night
rods
The ___________ permit vision in bright light needed for color.
cones
______________ is the ability of the eye to focus at different distances by changing the curvature of the lens
accommodiation
Sensation occurs when sensory receptors respond to environment stimuli by generating nerve impulses.
false
The receptor cells for sight are the rods and cones found in the _________ .
retina
When blood glucose levels rise, the pancreas produces insulin, which causes the liver to store glucose. The stimulus for insulin production is therefore inhibited and the pancreas stops producing insulin. This is an example of:
Negative feedback control of hormone production
Which of these glands release hormones that trigger short term stress responses?
adrenal medulla
Which of the following are chemical signals produced from fatty acids that have local effects on such things as menstruation pain, lowering of blood pressure, and platelet aggregation.
Prostaglandins
Which of these are hormones which have been associated with appetite control?
leptin
Which of the following is a hormone produced by the anterior pituitary?
growth hormone
Insulin lowers blood glucose level while glucagon, also a product of the pancreas, raises it. This is an example of:
