03.08 Module Three Exam (Notes)
A scientist runs a chemical analysis of two nerve tissues. Tissue A contains a greater composition of fat and protein than tissue B. What is the identity of the two tissues?
A = white matter; B = gray matter
Based on the figure above, which two parts of the eye are responsible for transducing visual information into neural impulses and transporting those neural impulses to the brain?
A and D
What part of the brain is responsible for conscious thinking and decision making?
Cerebrum
Which part of a reflex arc would connect a sensory neuron from the face and neck to a motor neuron in a lower section of the spinal cord?
Interneuron
During the process of nerve conduction, a person experiences an increase in synaptic transmissions. Which of the following is a likely contributor to this?
Drinking caffeinated beverages several times a day.
A person always feels hungry, even a short time after eating. This person also has high blood calcium levels. This person could have a disorder with which glands?
Hypothalamus; thyroid
A hormone attaches to a target cell at a receptor protein. What do you know about this hormone?
It is a non-steroid hormone
A hormone attaches to a target cell at a receptor protein. What do you know about this hormone?
It will not enter the nucleus.
Which of the following correctly identifies letter D on the diagram above?
Medulla oblongata
What is the correct order of a signal being transmitted across a neuromuscular junction?
Neuron—neurotransmitter—receptor protein—motor end plate
Which of the following is correctly paired with its function?
Sensory somatic nervous system—controls skeletal muscles
The ventral root is associated with which action of a reflex arc?
Stimulation of the effector
What is the structure labeled with the question mark?
Synaptic vesicle with neurotransmitter
Gustatory and olfactory refer to which of the following senses, in which order?
Taste and smell
Before Jane gives a presentation to her class, she gets very nervous and her heart begins beating faster than usual. Which statement best classifies this reaction?
The autonomic nervous system is creating an involuntary response to stimuli.
A steroid hormone approaches its target cell. Which will happen first?
The hormone will combine with proteins to form lipoproteins
A boxer is competing in a match. Which describes the roles of endocrine and neural controls as he boxes?
The nervous system transmits pain, while the endocrine system elicits the fight or flight response.
The structure labeled with "C" is called...
a ventral root
Parkinson's disease prevents the brain from properly sending motor signals to the consciously moved muscles of the body. This disease would therefore inhibit parts of the
peripheral nervous system
A person's kidneys start secreting renin. This hormone is known to
regulate blood pressure.
Exocrine glands...
secrete hormones into an attached duct
Sensory nerves are fibers that...
send signals toward the central nervous system
