what is a synapse.
The connection space between the dendrite of one cell and the axon of another cell
What structure in the mammalian brain is enlarged and is responsible for higher mental processes?
forebrain
What unique structural adaptations are found in the mammalian brain that allowed mammals to become adept at higher mental activities?
A higher degree of crevasses and folds in the neocortex that increases the surface area of the brain.
Which of the following statements about the cerebrum are true? (4)
It is the largest part of the human brain.
The gray matter is outermost.
The two cerebral hemispheres are connected by the corpus callosum.
The cerebrum coordinates the activities of the other parts of the brain.
Which part of the brain contains centers for the heartbeat and respiration?
medulla oblongata
What symptoms could result from a stroke to the right side of the frontal lobe?
The person could suffer the loss of motor control of the left side of their body, loss of memory, reasoning and judgment.
Which of the following eye conditions is NOT treated with corrective lenses?
cataracts
Which of the following sensations would involve a chemoreceptor?
Smell and taste
Which statement about chemoreceptors are true? (4)
Chemoreceptors are universally found in animals
concentrated on the auricles of the head in planaria.
found on antennae and mouthparts in insects and other arthropods.
thought to be the most primitive sensory receptor to have developed in animals.
Which of the following statements about photoreceptors are true (4)
Photoreceptors differ in complexity in different kinds of animals.
Eyespots in planaria allow the direction of light to be determined.
The simplest photoreceptors only recognize the presence and intensity of light.
A compound eye as seen in insects has many different visual units, each containing a lens.
What is the aqueous humor?
the fluid in the eye between the cornea and the lens
Since chemoreceptors are found in arthropods, crustaceans, vertebrates and all other animals it is believed that chemoreception is the most primitive sense. (T/F)
true

cornea-aqueous humor-pupil-lens-vitreous humor-retina.
The sclera is continuous with the
cornea
What kind of receptors are involved in hearing?
mechanoreceptors
