The vascular coat of the eyeball is called:

Conscious perception of vision probably reflects activity in the:
cortex of the occipital lobe
The cell body of a first order neuron will be located in the:

granular cell layer
Ventricular systole happens:
in a wave that begins at the apex and spreads toward the base
Which structure communicates the lateral ventricles to the third ventricle?
interventricular foramen
A thick midline ridge in the thyroid cartilage that is sometimes referred to as the Adam's apple is technically named the:
laryngeal prominence
Which type of general sense receptor detects pressure changes in walls of blood vessels and in portions of the digestive, reproductive and urinary tracts?
mechanoreceptors
The larger the receptive field, the __________ it is to localize the stimulus.
more difficult
Which of these types of receptors responds to pain stimuli?
nociceptors
Small muscle masses attached to the chordae tendineae are the:
papillary muscles
Blood is pushed out from the right atrium into the right ventricle (every last drop of it) by this muscle. Can you name the structure?
pectinate muscles
A special feature of fenestrated capillaries is that they have:
pores
Which structure prevents backflow into the right ventricle?
pulmonary valve
The abducens nerve _________.
supplies innervation to the lateral rectus muscle of the eye
The larynx is composed of ______________ big pieces of ____________ cartilage.
