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.
