Damage to which artery leads to loss of vision
a. cicle of willis
b. internal carotid
c. vertebral artery

When upper and lower canines contact what is the position of disc and condyle???

the artery which leads to loss of vision shd be (central artery of retina)which is a branch of ophthalmic div. of internal carotid artery
upper and lower canines contact only during the protruded contact position in which the condyles move downward and forward on the articular eminence

Max osmolarity in Kidney - It s'd be descending loop of henle, correct.? How can it be ascending when it is totally impermeable to water.?

ascending loop of henle multiplies the conc. of Nacl in the medullary interstitium by being impermeable to water and reabsorbing Nacl

or we can elaborate it by saying max. osmolarity in the kidney occurs in the medullary interstitium around ascending loop of henle

Lymphatic fluid from the area of infected tooth #32 will drain INITIALLY to which of the following nodes?

A. Buccal
B. Submental

Hey how did u come to tat conclusion ?? plzz explain

 

[porcelain258]

ans. shd be submandibular becoz it is clearly asking initially.....if it wd hv been ultimately .then shd be deep cervical

Booklet 1-B, Question 48

Pain originates in the pulp due to
1. free nerve endings primarily located in the center of the pulp
2. free nerve endings about the odontoblastic cells
3. free nerve endings in the cell-rich layer of the pulp
4. myelinated nerve fibers in the adjacent part of the dentin

Answer: 2

Does anyone know why the answer couldn't be 3? Is it because the cell-rich layer contains mostly fibroblasts? Is this question hinting at the hydrodynamic theory of pain in which movement in dentin tubules causes pain? Help!

[shuntyman]

thoracic splanchnic nerves pass through sympathetic chain without synapsing nd supply foregut and midgut via celiac nd aortorenal ganglion...... while white rami communicantes synapse at sympathetic ganglion chain to supply smooth muscles nd glands of body wall and in limbs.

Hope it make sense to you..
