General Senses include smell, touch, vision, hearing and equilibrium.

Receptor Cells are identified as:

The sense of hearing is classified by the ________ mode.

When it comes to the sensory pathway, you must be able to sense or detect a stimulus or a change in the quality or intensity of a particular stimulus in the environment.

The sensory pathway for the general senses typically involves conduction of action potentials generated in the receptors through the spinal cord to the ____ or ____where they synapse, and impulses are then relayed to specific areas of the cerebral cortex for conscious sensory interpretation.

The sensory pathways for the special senses are varied, but also ultimately end in specific sensory areas of the _____

Two-point discrimination

Lesions to the ____ of the brain will impair two-point discrimination.

PROPRIOCEPTORS: When found near the point of junction between ___ and ____ and others found deep within the ____

General sense disorders are caused by :

Keratitis is inflammation of the cornea and affects the ability to focus an image onto the _____

Pupils are controlled by _____

Lens are held in place by a ligament attached to an involuntary muscle called the

Ganglion cells assists our body’s external clock to synchronize themselves to the daily, monthly, and seasonal rhythms of our internal environment.

Fluids

Name of watery fluid in front of the lens (in the anterior chamber of the eye)

_____occurs as light passes through the cornea, the aqueous humor, the lens, and the vitreous humor on its way to the retina

No rods or cones are present in the area of the retina where the optic nerve fibers exit

Myopia: Nearsightedness. When our eyeballs are _____ and the image focuses somewhere in the _____of the retina rather than directly on it. Producing a fuzzy image.

Astigmatism

Longtime exposure to ultraviolet (UV) radiation in sunlight may cause the lens to become hard, lose its transparency, and have regions that become “milky” in appearance.

Caused by bacteria such as Staphylococcus and Haemophilus

Diabetes causes small hemorrhages in retinal blood vessels that disrupt the ____ supply to the photoreceptors

Retinal Degeneration is caused by a deficiency in Vit____

Cerebrovascular Accident (CVA), or stroke, can cause vision impairment when damage occurs in the one of the regions  of the ____ that process visual information

External ear includes

Those who suffer with GOUT can experience:

The skin of the acoustic canal, especially in its outer one third, contains many short hairs and ceruminous glands that produce a waxy substance called _____

Auditory ossicles (lateral to medial)

The ____ presses against a membrane that covers a small opening called the oval window

Bony labyrinth includes (select all that apply)

Mechanoreceptors for our sense of balance, or equilibrium, are in the saclike vestibule and the ___ semicircular canals of the inner ear

Equilibrium: The sensory cells are stimulated when a change in movement of the head causes the ____ to move differently, thus causing the crista ampullaris to sway with more or less force

Refers to the blocking or sound waves as they travel through the external and middle ear to the sensory receptors of the inner ear

An inherited bone disorder that impairs conduction by causing structural irregularities in the stapes.

Equilibrium disorders are characterized by (select all that apply):

The taste buds are the sense organs of taste. They contain both supporting cells and chemoreceptors called ____cells. These cells generate the nervous impulses ultimately interpreted by the brain as taste

Physiologists originally counted only four “primary” taste sensations (select all that apply)

The olfactory receptors are extremely sensitive and respond quickly to even very slight odors. However, they are also easily ____— a fact that explains why odors that are at first very noticeable are not sensed at all after a short time. This decrease in receptor sensitivity is called adaptation
