There are five types of sensory receptors-chemoreceptors, pain receptors, thermoreceptors, me change receptors, and photo receptors. What is each of these receptors sensitive to?-Photoreceptors | Light |
The Ability of the nervous system to become less responsive to a maintained stimulus | Sensory adaptation |
In touch and pressure, what are the three types of nerve ending and their functions?-Free nerve endings | Give sensation of itching or pain |
In touch and pressure, what are the three types of nerve ending and their functions?-Tactile corpuscles | Interpret light touch |
In touch and pressure, what are the three types of nerve ending and their functions?-Lamellated corpuscles | Give sensation to deep pressure |
With temperature sensation, what are the sensations felt at different temperatures-warm receptors | Sensitive to 77°F or above, sensation of burning occurs at 113°F |
With temperature sensation, what are the sensations felt at different temperatures-cold receptors | Sensitive to 50°F-68°F, sensation of freezing occurs at 50°F or below |
What is the purpose for pain | To protect the body |
What is referred pain | It feels as if the pain is coming from a body part other than the one being stimulated |
What has to happen to the odorant molecules that enter the nose in for the olfactory organs to smell | They dissolve in fluid and bind to the receptors |
*Explain how taste buds taste. Describe parts of the taste bud and what needs to bind to the taste receptors | Taste buds are taste organs that Have 50-100 gaste cells with an opening called a taste pote and have tiny taste that stick out of the pores |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 1 | Sound waves enter External acoustic meatus |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 2 | Sound waves cause the eardrum to reproduce vibrations coming from sound source |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 3 | Malleus vibrates causing the incus to vibrate, causing tjw stapes to vibrate |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 4 | When stapes vibrate against the oval window where they transfer them vibration to perilymph cells |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 5 | This movement travels to the endolymph and mover the hair cells |
What is the path that the sound waves must travel through the ear in order for us to hear-Step 6 | The hair cells stimulate an impulse that travels to the auditory complex of the temporal lobe. |
What is the static equilibrium, what are the organs and how do they work | It senses the position of the head, the macula organiza has hair cells that are stimulated when the head moves |
What is the dynamic equilibrium, what are the organs and how do they work | It detects motion and Aida in maintaining balance, the crista ampularis has sensory receptors that are located in gel-like fluid that when it moves it bends the receptors and stimulate the neurons |
Describe and give the function of the followinbg parts of the eye:eyelid | Has four layers and protects the eye. |
Describe and give the function of the followinbg parts of the eye-Lacrimal apparatus | Is made of glands and ducts that carry tears to the nasal cavity |
Describe and give the function of the followinbg parts of the eye:extrinsic muscles | Has six muscles that move the eyes in various directions |
Describe and give the function of the followinbg parts of the eye:cornea | Is transparent and acts as the window of the eye |
Describe and give the function of the followinbg parts of the eye:schlera | Is made up of collagenous and elastic fibers and protects the eye. |
Describe and give the function of the followinbg parts of the eye:choroid coat | Is the back layer of the eye and contains melanocytes that cause the inside of the eye to be dark to absorb excess light |
Describe and give the function of the followinbg parts of the eye:lens | Lies behind the iris and pupil, has fibers that are transparent and let light through |
Describe and give the function of the followinbg parts of the eye:iris | Gives the eye color |
Describe and give the function of the followinbg parts of the eye:retina | Contains photoreceptors |
Describe and give the function of the followinbg parts of the eye:pupil | A circular opening in the center of the iris |
What is accommadation | Is when the ciliary muscles and suspensory ligaments help the lens to adjust its shape to focus on objects in the distance and up close |
How are photopigments involved in creating nerve impulses for the sense of light | A light sensitive pigment in rods decomposed in the presence of light triggering a series of reactions that initiate thw nerve impulses |
