senses (smell, taste, and so on)

the sense of smell

dissolved chemicals that stimulate the olfactory receptors

sensory neurons withing the olfactory organ

these nerve axons collect in the cribriform plate and carry impulses along the olfactory tract

Axons leaving the olfactory epithelium collect into bundles in here

the first synapse of smelling occurs here

axons leaving the olfactory bulb carrying impulses follow this to the cortex

The final place in the olfactory cortex the smells are integrated (x2)

the sense of taste

the other name for gustatory receptors distributed across the tongue, throat, and larynx

one type of taste sensation that is characterized by pleasant savory tastes.

this taste sensation receptors are sensitive to amino acids and small peptides and nucleotides

This sensory receptor of the pharynx sends information to the hypothalamus and affects water balance and the regulation of blood volume

the primary taste sensations are

G proteins found in taste receptors that experience sweet, bitter and umami sensations are called

gustatory cells are stimulated by

Where are the sensory cells located for equilibrium and hearing?

What are the receptor cells of the internal ear called

Why are hair cells called "hair cells"

What type of sensory receptor are hair cells

what is the name of the support cells associated with the hair cells

the ear is divided into three anatomical regions, what are they

This structure consists of elastic cartilage and is used to collect sound waves and funnel them into the external acoustic meatus

this is the visible portion of the ear which collects and directs sound waves toward the middle ear

this portion of the ear goes by two names that describe the air filled cavity separated from the external acoustic meatus by means of the tympanic membrane . what are the two names

this portion of the ear contains the sensory organs for hearing and equilibrium

this is the passage way within the temporal bone thru which sound waves travel from the external ear to  the tympanic membrane

these are glands which secret ear wax

what is the wax in the ear called

what are the two main functions of the cerumen

this structure known as the eardrum lies at the end of the external auditory meatus and separates the external ear from the inner ear

this structure permits pressure equalization on either side of the tympanic membrane

what is a middle ear infection called

the inner ear contains three auditory ossicle bones. in order what are they

this is a collection of fluid filled tubes and chambers inthe inner ear

the membranous labyrinth contains fluid called

this is a shell of dense bone that surrounds and protects the membranous labyrinth

the bony labyrinth is composed of three parts which are

this part of the inner ear provides equilibrium sensations by detecting rotation, gravity, and acceleration.

this portion of the vestibular complex consists of three semicircular canals which detects rotational movements of the head in three different planes

this specific portion of the vestibular complex consists of two chambers with receptors that are sensitive to head position relative to gravity and linear acceleration

the movement of the stapes at the oval window generates pressure waves that stimulate hair cells at specific locations alonf the length of this structure and is used in hearing*

the hair cells of the utricle and saccule are clustered in oval structures called

in regards to the eye located in the retina, these see colors of black and white, highly sensitive, they enable us to see in dimly lit rooms, at twilight and pale moonlight.

this part of the retina provides us with color vision, giving us sharper, clearer images. but these require more light to see.

this light sensitive pigment is found inthe rods

this light sensitive pigment is found in the cones

this kind of vision is less than 20 ft. away and the lenses can actually change and adjust

the region of the ampulla within the ear that contains the receptors is known as the

in regards tothe ear each crista ampullaris is bound to a flexible gelatinous structure called the

the fluid found in the ear is called

hair cell processes are bound to gelatinous mebrane called

the otolithic membrane contains densely packed calcium carbonate crystals called

what are the accesory structures of the eye

this is a transparent area on the surface of the eye through which light travels to the inner eye

this is the opening at the center of the colored iris which light passes into the eye after it passes the cornea

this is the covering of the inner surface of the eyelids and outer surface of the eye

this structure produces, distributes and removes tears.

the lacrimal apparatus is composed of what six structures

this structure produces tears that lubricate, nourish, and oxyginate the corneal cells

this is an antibacterial enzyme found in tears

this structure delivers tears from the lacrimal gland to the space behind the upper eyelid

this structure consists of two small pores that drain the lacrimal lake

this is a small canal that connects the lacrimal puncta to the lacrimal sac

this structure is a small chamber that nestles within the lacrimla sulcus of the orbit

this structure orginates at the inferior tip of the lacrimal sac and allows tears to pass through it into the nasal cavity

what is the name of the disease which causes inflamation of the conjuctiva

the wall of the eye has three layers

the outer most layer of the eyeball which consists of the cornea and sclera is

what are the three main functions of the fibrous layer

this layer contains numerous blood vessels, lymphatic vessels, smooth muscles of the eye

this is the inner most layer of the eye where the light energy is collected

what are the 4 functions of the vascular layer

the vascular layer is composed of three structures

this stucture gives eyes their color and control the pupil size

this structure acts as an anchor for the suspensory ligaments which hold the lens in place

this structure is covered by the sclera and has capillary network that delivers nutrients to the neutral tissue within the neutral layer.

these cells within the eye are sensitive to light

the ciliary body and lens divides the eye into two structures what are they

the anterior cavity of the eye is divided into two structures

what fluid is found in the anterior cavity

what fluid is found in the posterior cavity
