near a tendon. tension in muscles (proprioception). encapsulated

Question 15

What creates precision in touch/feeling

Answer 15

more neuron receptors in a receptive field

Question 16

What’s referred pain

Answer 16

pain from visceral areas manifesting itself in superficial sites. (coming home to a messy house and asssuming its the bad kid)

Question 17

Gustation

Answer 17

taste

Question 18

Lingual papillae

Answer 18

bumps on ur tongue

Question 19

Filiform

Answer 19

no taste buds in them. Tiny spikes. All over tongue

Question 20

Foliate

Answer 20

ridges on tongue sides. Buds on children but not in adults

Question 21

Fungiform

Answer 21

mushroom shaped bumps, have taste buds. Dispersed throughout tongue

Question 22

Vallate

Answer 22

large bumps that make a V at the back of the tongue. Have taste buds

Question 23

What two parts of the tongue have taste buds in (adults)

Answer 23

Fungiform and Vallate

Question 24

Structure of taste buds

Answer 24

Taste cells with taste cells in a pore. The taste hairs have chemo receptors that detect specific compounds. Synaptic vesicles released to brain. Brain interprets based on the compounds detected.

What nerves are important in detecting taste

Answer 25

Facial (anterior tongue), Glossopharyngeal (posterior tongue), Vagus (palate, pharynx, epiglottis)

Question 26

Answer 26

Medulla oblongata
