Exam 16: Nervous System: Senses

Accommodation of the lens occurs when

These receptors respond to changes in temperature.

The gelatinous mass inside of the eye is called the

Changes in the external and internal environment are ________ that are detected by the sensory system.

-In this illustration of the ear,what structure does number 1 indicate

Phototransduction is the process in which

Phasic receptors for light touch and texture are

The vascular tunic of the eye has three distinct regions.From anterior to posterior what are they A: Ciliary body B: Choroid C: Iris

When light strikes a photoreceptor it

The eye measures about ________ in diameter.

Where is the saccule located

Which sequence correctly traces the pathway of aqueous humor in the eye A: Aqueous humor is secreted by epithelial ciliary cells. B: Aqueous humor is released into the posterior chamber. C: Aqueous humor is drained into the scleral venous sinus. D: Aqueous humor washes over the lens and then passes through the pupil into the anterior chamber.

This receptor detects continuous deep pressure and distortion of the skin.

Visual pathways include axons that project from the optic tracts to the superior colliculi.

As the eye adjusts to focus on a near object,the cornea must change shape because the lens is unable to.The shape (and therefore refractive index)of the cornea is fixed and the lens is responsible for changing shape when the eye transitions to view a near or far object.The ciliary muscles are responsible for controlling lens shape.

A person having a heart attack may feel pain along the medial side of the left arm.This pain is known as

These receptors respond to touch,pressure,vibration,and stretch.

-In this sagittal view of the eye,what space does number 10 indicate

Olfactory receptor cells are _____ neurons.

There are four types of encapsulated receptors.Select the exception.
