Question 7: Diabetic retinopathy develops because abnormal blood vessels grow into the space adjacent to the neural part of the retina, causing cellular damage and ultimately blindness. Which of the following cells form the deepest layer of the neural part of the retina?
amacrine and horizontal cells
rods and cones
Question 8: The acronym PRL stands for the hormone named
Question 9: Identify the neuron structure labeled “C”.
Question 10: Which part of the diencephalon relays and process sensory information?
Question 11: Identify the type of neural circuit labeled “E”?
Question 12: Amyotrophic lateral sclerosis (ALS) is also known as_______________.
Lou Gehrig’s disease
Question 13: Tim has suffered a vasovagal loss of consciousness, commonly known as fainting. Environmental triggers, including the smell of the anatomy lab and the sight of the cadaver, caused a momentary malfunction of his autonomic nervous system (ANS). How is the structural organization of the ANS different from or similar to that of the somatic nervous system (SNS)?
They are different. In the ANS, central nervous system motor neurons synapse with and exert direct control over the visceral effectors.
They are different. In the ANS, motor neurons of the central nervous system do not directly control visceral effectors. They synapse with visceral motor neurons in ganglia, and the ganglionic neurons control the visceral effectors.
Both the ANS and the SNS have the same organization: an upper motor neuron that synapses with a lower motor neuron that directly innervates muscle.
Both the ANS and the SNS have the same organization: a visceral motor neuron that synapses with a preganglionic neuron that synapses with the ganglionic neuron that innervates the visceral effectors.
Question 14: Which of the following stimuli would NOT be monitored by special sensory receptors?
Question 15: Underproduction or tissue insensitivity of which hormone causes AIDison’s disease?
Question 16: Which of the following is NOT one of the three classes of mechanoreceptors?
Question 17: When a person faints, their sympathetic division of the ANS fails, while the parasympathetic division goes into overdrive. Parasympathetic stimulation of the vagus nerve causes the individual’s heart rate to slow, the force of contractions to decrease, and blood pressure to drop. As a result, blood flow to the brain decreases, causing a fainting episode. Which part of the brain is critical for maintaining consciousness through its interactions with the cortex?
the reticular activating system
general interpretive center
Question 18: In a condition called detached retina, the neural part of the retina separates from the pigmented part. Blindness may result if blood supply to the photoreceptors cannot be restored. These photoreceptors are called?
rods and cones
amacrine and horizontal cells
Question 19: When blood glucose levels are high
the pancreas releases insulin
the pancreas releases glucagon
the liver releases insulin
the liver releases glucagon
Question 20: Pain receptors located in the epidermis are called _______________.
Question 21: Years of illegal drug use have left a patient with anterograde amnesia. Which of the following regions is probably affected?
all of the answers are correct
Question 22: The scientific term for eyelid is
Question 23: Type 1 diabetes mellitus is related to which the underproduction of which hormone?
Question 24: Which ion causes repolarization of the neuron during an action potential?
Question 25: Identify the cranial nerve labeled “E”.
Question 26: Which glial cells are most directly associated with the formation of CSF?
Question 27: Which of the following tactile receptors is a diagram of a Ruffini corpuscle?
Question 28: According to the Clinical Note “Alzheimer’s disease”, which is NOT true concerning early-onset Alzheimer’s?
it can be caused by long-term aspirin use
early-onset accounts for less than 5% of Alzheimer’s cases
it has been linked to genes on a few different chromosomes, including chromosome 21
a majority of individuals with Down’s syndrome develop it
Question 29: Tears are lacrimal secretions which contain 2 bactericidal proteins called
IgG and lysozyme
IgG and appozyme
IgA and appozyme
IgA and lysozyme
Question 30: Primary endocrine disorders may be due to damage to the hormone producing organ. If a person has damage to the thyroid gland from repeated exposure to radiation therapy, which of the following is least likely to be part of a primary endocrine disorder for this individual?
none of the answers are correct
hyposecretion of calcitonin
hyposecretion of T3 and T4
decreased osteoblast sensitivity to calcitonin
Question 31: Assessing spinal nerve damage may involve the use of a vibration fork that is tapped along segments of the spinal nerve pathway. Which type of sensory receptor detects vibrations?
Question 32: While out for a walk, Mary suIDenly meets an angry dog. Which division of the autonomic nervous system is responsible for the physiological changes that occurs as she turns and runs?
Question 33: Identify the eye structure labeled “E”.
Question 34: Which endocrine gland produces epinephrine and norepinephrine?
Question 35: An individual with high blood pressure is given medication that blocks beta receptors. How could this medication help correct the person’s condition?
by increasing sympathetic stimulation of tissues containing those cells (ie: smooth muscle, cardiac muscle)
none of the answers are correct
by decreasing or preventing sympathetic stimulation of tissues containing those cells (ie: smooth muscle, cardiac muscle)
by decreasing or preventing parasympathetic stimulation of tissues containing those cells (ie: smooth muscle, cardiac muscle)

an increase in intraocular pressure due to the inability of aqueous humor to drain
elongation of the eyeball
