Somatic & Special Senses
| Question | Answer |
|---|---|
| How many special senses are there? | 5 |
| How many thermoreceptors, that detect the temperature of skin, are there? | There are 2 types: cold receptors and warm receptors |
| Where are warm receptors found? | Dermis |
| What do proprioceptors detect? | Body position and movement |
| Proprioception means awareness of | Position |
| Olfactory receptors are found | Only in the inferior portion of the nasal cavity |
| Physical support, nourishment and electrical insulation for olfactory receptors is provided by | Supporting cells |
| What does the olfactory tract do? | Projects to the limbic system and hypothalamus |
| Taste buds are found on the | Soft palate, Epiglottis, Pharynx |
| Which papillae do not contain taste buds? | Filiform |
| Which nerves serves in a gustatory function? | Vagus |
| List the order in the flow of tears? | Lacrimal gland, excretory lacrimal duct, superior of inferior lacrimal canal, lacrimal sac, nasolacrimal duct, nasal cavity |
| How many extrinsic eye muscles are responsible for moving the eye? | Six |
| This is the transparent coat that covers the iris. | Cornea |
| The main function of this structure is to regulate the amount of light entering the eyeball through the pupil. | Iris |
| This lies between the lens and the retina. | Vitreous chamber |
| Binocular vision | Gives depth perception |
| What is the first step in visual transduction? | absorbing light by photopigments |
| Organs for equilibrium? | semi-circular canals, saccule, utricle |
| List 3 somatic senses: | Pain, Proprioception, Temperature |
| Rapidly-adapting touch receptor in the skin? | Meissner corpuscles |
| Where are cold receptors found? | Epidermis |
| What do nociceptors detect? | Pain |
| What do Proprioceptive sensations tell us in the body? | have receptors embedded in muscles and tendons, are from slowly adapting receptors, allow us to determine position of body structures |
| These are found in the articular capsules of synovial joints. | Kinesthetic receptors |
| These cells provide for the sense of smell. | Olfactory cells |
| These are the stem cells in the olfactory epithelium. | Basal cells |
| These cells provide for the sense of taste. | Gustatory cells |
| List 3 accessory structure of the eye: | Lacrimal apparatus, Eyelashes, Eyebrows |
| This tough outer coat protects the inner parts of the eyeball. | Sclera |
| This darkly pigmented structure reduces light reflection within the eyeball. | Choroid |
| Which of the below receptors function in bright light and provide color vision? | Cones |
| Where are the organs for hearing and equilibrium or balance located? | Inner ear |
| The organ of hearing is located within the | Cochlea |
