Exam 10: The Nervous System: Sensory Systems

The anterior portion of the semicircular canal detects acceleration in which direction?

The detection of sweet by taste receptors occurs via the binding of organic molecules to receptors on the cell membrane activating that ultimately causes a _.

What molecules within the mucus of the olfactory epithelium carry odorants to the receptor on the cilia?

Bending of stereocilia of a hair cell toward the kinocilium causes (depolarization / hyperpolarization)of the hair cell.

(Rods / Cones)are more sensitive to light.

The bone overlying the olfactory epithelium is called the

Frequency of sound is coded for by the

The absence of pain, but not other somatosensations, is called (anesthesia / analgesia).

Which of the following is the correct order of communication of visual information in the retina?

The point on the retina with greatest visual acuity is the optic disk.

The amount of light that impinges on the retina is primarily regulated by what structure?

Which receptor type is used to detect free hydrogen ion content of blood?

Each taste receptor cell is specific to only one of the four primary tastes.

Which receptor type is used to detect increases in temperature between 30°C and 43°C?

What are sensory receptors that respond to tissue- damaging stimuli or stimuli that have the potential to damage tissue?

A (concave / convex)lens causes light waves to converge onto a focal point.

Cytokines released during illness can cause a person to be more sensitive to pain.

What are the strands of connective tissue that connect the lens to muscles for accommodation called?

What is a condition where light, originating from a distance, is focused in front of the retina?

Both the auditory and vestibular systems rely upon to detect movement of fluid within the ear.
