general senses

receptors widely distributed throughout the body

Special senses

Receptors in the head

Mechanoreceptor

Touch pressure

Thermoreceptor

Temperature

Chemoreceptors

(Chemicals) smell taste

Chemo receptors are

Special sense

Nociceptors are

Pain receptors

Chemoreceptors respond to

Tissue damage

Nervous tissue of brain lacks

Pain receptors

Acute pain

Sharp, fast, and localized

Chronic pain

Unmylinated, slow, last longer

Referred pain

Pain and organ is perceived as cutaneous pain

Special senses rely on

no neurons

Special senses are confined to

The head

Transduction can be

Physical or chemical

Olfactory neurons

Bipolar, chemoreceptors

Stem cells are

Supporting cells

Olfactory tract is the only sensory pathway that bypasses

The thalamus

Olfactory tract is located in the

Temporal lobe

taste buds papile are

Located on the tongue

Primary gustatory pathway in parietal lobe

Thalamus

Lacrimal glands

Ducts that reduce tears to lubricate and moisten

Lysozyme

Enzyme with an antibacterial properties

Sclera

Posterior white portion

Rectus

Straight muscle

The vascular layer is

Pigmented

The ciliary body

Holds lens

Aqueous liquid is

Waterlike

The neural layer is also known as

retina

Choroid coat

Melanocytes to keep eye dark inside

Superficial layer

Photoreceptors

Deep layer

auditory tube (pharygotymapic tube)

Middle ear to the throat

Semicircular canals

Detect rotational movement of head

Conductive deafness

Transmission of vibration to the inner ear

Sensorineural deafness
