General Senses and Special Senses
1) sensory receptors based on stimulus origin
Interoceptors
Stimulus from interior of body
Location
Internal organ
Proprioceptors
Sensitive to stimulus from muscle, tendons, ligaments joints
Laction
inner ear, muscles, tendons, and joints
Exteroceptors
Stimulus from the environment
Location
Skin, Special sense organs
2) sensory receptors based on type of stimulus
Chemoreceptor
sensor to chemical- smells or taste: in your blood
Nociceptor
sensor to pain
Photoreceptor
sensor to light
Mechanoreceptor
Pressure, touch, vibration, stretch
Baroceptor
sensor to pressure, sensitive to blood pressure
Thermoreceptor
Sensor to tempature
3) gross and microscopic anatomy of the eye
Vascular layer
choroid
Vascular-nourishes other tunic. Absorbs/prevent light from scattering. Continuous with ciliary body
Ciliary body muscle and changes the shape of lens
Black
Inner Layer
Contains photoreceptor- axons from receptors
Tan
Converge to become optic nerve
Fibrous Layer
Sclera (D.C.T)
Protective, anchor for muscle, and gives shape
cornea
Transparent- allow light into eye and help focus light
3.Location and Function of lens and iris of the eye
Lens
Function
Focusing light on retina
Location
Posterior to the iris
Iris
Function
Dilate or constrict to allow more/less light; made of Smooth muscle
Location
Posterior to cornea
Pupil
Opening
2.Compare/Contrast function of rods and cones
Rods
Have more rods than cones
sensitive to light and darkness/light
used dim light
Cones
color vision-bright light
4: Location/function of optic disc, macula lutea, and fovea centralis
Macula lutea
Posterior pole; sharpest vision only cones
Fovea centralis
Center of macula lutea
Optic disc
where axons converge form optic nerve; no photoreceptors "blind spot"
5: Copamare/contrast posterior and anterior cavities
Anterior Segment
Much smaller/filled aqueous humur
Anterior to posterior Segment-cornea
Transmil light
Nourishes lens/cornea
No Blood Vessels
Posterior chaber
Anterior segment
Iris
Anterior chamber
Iris
Cornea
Maintain normal pressure/shape
Posterior Segment
Filled with vitrous humur
Take most of spaces
Viscous liquid
Tranmil light
Supports retina/lens
maintains normal pressure/shape
