fovea

The area of the eye with the greatest visual acuity is the:

external iliac artery

The femoral artery originates from the:

more difficult

The larger the receptive field, the __________ it is to localize the stimulus.

endocardium

The lining of the heart chambers is called the ________.

cardiac cycle

The period between the start of one heartbeat and the beginning of the next is a single _______.

sclera

The white, outer tough connective tissue covering of the eyeball is called:

thinner

Veins are much more easily distended under pressure than are arteries because their walls are ________ and contain a lower proportion of smooth muscle fibers.

lowest

right ventricle pumps deoxygenated blood into the lungs

nociceptors

Which of these types of receptors responds to pain stimuli?

mitral valve

Which structure prevents backflow into the left atrium?

tympanic membrane

Which structure separates the external auditory canal form the middle ear?

sensory adaptation

occurs when a receptor becomes so accustomed to the stimulation that it stops gathering impulses.
