Looks like we have a shortage of Mader Quiz 6 here, so here is my contributions to this great site. Enjoy!
Question 1 of 30

Question 8 of 30
In higher vertebrates, control of sleep is chiefly governed by which part of the brain?
A. Cerebellum

Question 9 of 30
The outer portion of the spinal cord which acts as a superhighway by continuously passing information between the brain and the rest of the body is referred to as:
A. The thalamus
B. White matter C. The corpus callosum
D. Gray matter
E. The meninges
Feedback: A cross section of the spinal cord reveals that it is composed of a central portion of gray matter and a peripheral region of white matter. Myelinated long fibers of interneurons that run together in bundles called tracts give white matter its color. These tracts connect the spinal cord to the brain. Like a busy superhighway, these tracts continuously pass information between the brain and the rest of the body.
Question 10 of 30
The part of the brain which determines when a situation calls for fear would be:
A. The hypothalamus
B. The amygdala C. The pons
D. The medulla oblongata

Feedback: The amygdala adds emotional overtones to memories. For example, the smell of smoke not only warns us that the hotel is on fire, but also creates great anxiety.
Question 11 of 30
The bones of the ear:
A. Respond to changes in the position of the head
B. Are connected to the tectorial membrane and oval window
C. Are directly connected to the auditory nerve
D. Are named the malleus, incus, and otolith
E. Transmit sound waves Feedback: Good job!
Question 12 of 30
Which of the following receptors are located in the hypothalamus and the skin?
A. Chemoreceptors
B. Thermoreceptors C. Nociceptors
D. Mechanoreceptors
E. Electromagnetic receptors
Feedback: Good job!
Question 13 of 30
The sensory receptor for hearing would be classified as which of these?
A. A nociceptor
B. A mechanoreceptor C. A chemoreceptor
D. A thermorecpetor
E. An electromagnetic receptor

A. Choroid cells
B. Cone cells
C. Bipolar cells
D. Ganglion cells

Feedback: Good job!
Question 18 of 30
The knee is an example of a(n):
A. Hinge joint B. Immovable joint
C. Ball-and-socket joint
D. Fibrous joint
