The Sensory System
| Question | Answer |
|---|---|
| What is sensory receptor? (10-1 p.202) | A sensory receptor is a part of the nervous system that detects a stimulus |
| What are some categories of sensory receptors based on the type of stimulus? *hint 4* (10-2 p.202) | Chemoreceptors- respond to chemical in solution; Thermoreceptors- respond to temperature; Photoreceptors- respond to light; Mechanoreceptors- respond to movement |
| How do the special and general senses differ in location? (10-3 p.202) | General senses are widely distributed; Special senses are specialized sense organs |
| What happens when a sensory receptor adapts to a stimulus? (10-4 p.202) | It fails to respond |
| What are 5 structures that protect the eye? (10-5 p.204) | Skull bones Eyelids Eyelashes/Eyebrows Lacrimal (tear) glands Conjunctiva (thin membrane/mucus eye lubrication) |
| What is the function of the extrinsic eye muscles? (10-6 p.204) | Pulls on the eyeball so that both eyes center on one visual field aka CONVERGENCE |
| What cranial nerve carries impulses from the retina to the brain? (10-7 p.204) | CN. II OPTIC NERVE (sensory) |
| What are the three tunics of the eyeball? (10-8 p.208) | Nervous- INNERMOST; Vascular- MIDDLE; Fibrous- OUTERMOST |
| What are the structures that refract light as it passes through the eye? *hint 4* (10-9 p.208) | Cornea; Aqueous humor; Lens; Vitreous |
| What is the function of the ciliary muscle? (10-10 p.208) | Contracts and relaxes to regulate the thickness of the lens and allow accommodation for near and far vision |
| What is the function of the iris? (10-11 p. 208) | Adjusts the size of the pupil to regulate the amount of light that enters the eye |
| What are the receptor cells of the retina? (10-12 p.208) | Rods and Cones |
| What are the 3 divisions of the ear? (10-13 p.214) | Outer; Middle; Inner; |
| What are the name of the ear ossicles, and what do they do? (10-14 p.214) | They transmit sound waves from TYMPANIC membrane to the INNER ear 1. Malleus 2.Incus 3.Stapes |
| What are the two fluids found in the inner ear and where are they located? (10-15 p.214) | 1.Perilymph: found around the membranous labyrinth in the bony labyrinth 2.Endolymph: found in the membranous labyrinth |
| What is the name of the hearing organ, and where is it located? (10-16 p.214) | Spiral organ (organ of Corti); In the cochlear duct w/in the cochlea |
| Where are the receptors for equilibrium located? (10-17 p.214) | In the vestibule and semicircular canals of the inner ears |
| What are the special senses that respond to chemical stimuli? (10-18 p.215) | TASTE and SMELL |
| What are the 5 examples of general senses? (10-19 p.218) | Touch; Pressure; Temperature; Position (proprioception); Pain |
| What are proprioceptors and where are they located (10-20 p.218) | Receptors that respond to change in position. Located in: 1.Tendons 2.Muscles 3.Joints |
