Step-by-Step Solution:
Step 1 of 3

4/19/2016 The ​Special Senses​ are thesenses​ that have specialized organs devoted to them: ​ vision (the eye) hearing​ and balance (the ear, which includes the auditory system and vestibular system) ​ smell (the nose) taste (the tongue) Vision­ The Eye ­ Fibrous Tunic­ area outside of the eye 1. Sclera­ the white of the eye­ is in the posterior ⅚ of eye 2. Cornea­ clear part of eye­ is in anterior ⅙ of eye Vascular Tunic­ ​ heavily pigmented tunic that prevents light scattering within the eye. Parts: 1. Choroid­ blood vessels. Dark­ posterior ⅚ of eye 2. Ciliary Body ­ Smooth muscles: suspensory ligaments, lens ­ Ciliary Process 3. Iris ­ Muscular diaphragm ­ Controls amount of light that lets in ­ Gets bigger and smaller ­ Posterior Segment: comprises most of the eye­ vitreous humor gel→ shapes eye. ­ Anterior Segment: anterior chamber and a posterior chamber. Anterior chamber is anterior to iris, posterior chamber is posterior to the iris. Filled with aqueous humor. ­ Ciliary Process→ Posterior Chamber→ Anterior Chamber→ Scleral Sinus ­ *Glaucoma­ condition where there is increased pressure on the eye Retina 1. Pigmented layer 2. Nervous tissue layer Photoreceptors Bipolar cells Ganglion cells Photoreceptors 1. Cones­ 3 types: Red, Green, Blue a. Found in high light levels b. Located in fovea centralis macula c. Wiring: more one to one with bipolar cells than rods 2. Rods­ Black and white a. Work best in low light levels b. Periphery Optic Disk ­ Aka blind spot ­ Where ganglion cells are exiting the eye Some Vocab: Refraction: bending of light one substance to another Accommodation: change in curvature of the lens for close up vision Myopia: near sighted Hyperopia: farsighted Eyelid: contains tarsal glands. Secrete oily substances, cysts form when infected. ­ Eyelash: sebaceous glands. Sty formed when infected. ­ Conjunctiva: mucous membrane, conjunctivitis occurs when infected. ­ Lacrimal glands­ produces tears, consists of: ­ Lacrimal canal ­ Lacrimal sac ­ Nasolacrimal duct Photoreceptors ­ Outer segment of photoreceptor­ embedded in pigmented layer ­ Disc ­ Membrane proteins­ opsins ­ 3 opsins in cones ­ 1 opsin in rods ­ Rhodopsin (in rods) ­ Opsin­cis­retinal: in the presence of light, also there are high levels of GMP present. Aka bleaching→ Opsin + all trans retinal­ increase cGMP breakdown, low GMP present. Dark: 1. cGMP will open Na and Ca ion channels. This will cause photoreceptors to depolarize. 2. Voltage gated Ca ion channels open 3. This releases a neurotransmitter/ an inhibitory neurotransmitter 4. Causes inhibitory postsynaptic potential in bipolar cells→ hyperpolarized 5. Hyperpolarized 6. So, no neurotransmitter is released Hearing and Balance­ The Ear ­ Outer, Middle, and Inner Ear Outer Ear ­ Pinna: collects sound ­ External auditory canal­ contains ceruminous glands (which has cerumen­ earwax) Middle Ear ­ Air filled ­ Tympanic membrane­ eardrum ­ Connected to malleus (hammer), incus (anvil), and stapes (stirrup) ­ Synovial joints connect the malleus, incus, and stapes. Inner Ear ­ Fluid filled ­ Cochlea­hearing ­ Semicircular canals­ dynamic balance ­ Vestibule­ static balance ­ Oval window­ stapes ­ Round window ­ Osseous Labyrinth­ little canals and tubes ­ Inside there is a membranous labyrinth ­ Endolymph is the term for inside of membranous ­ Perilymph is the erm for outside of membranous Spiral organ of corti ­ Hair cells ­ Tectorial membrane Sound ­ Pitch: frequency of sound waves ­ Loudness: magnitude of sound waves ­ High pitch is at the base of the cochlea ­ Low pitch is at the apex of cochlea ­ Static Balance: vestibule ­ Giving info concerning the position of the head ­ Maculae: receptor organ, hair cells ­ Otolithic membrane: otolith­ ear stone ­ Dynamic Balance: semicircular canal ­ Crista­ hair cells ­ Cupula­ gel like substance Smell­ ​ The Nose ­ Detects chemicals in the air ­ Receptors (dendrites) embedded in mucus ­ Chemical­ dissolve mucus ­ Bind to receptors (ion channels) ­ About 500 receptors that bind to 500 different molecules ­ We can detect 10,000 different smells
