How can this PLR (pupillary light reflex) help you determine whether the lesion is in the eye itself or elsewhere?

Answer:

Pupillary light reflex refers to the contraction that the pupils present when they light up. In cases of injury to the optic nerve, when the eye where the injured optic nerve is illuminated, since it cannot conduct the stimulus to the brain, neither pupil closes.

Explanation:

Pupillary light reflex refers to the reaction that causes the pupil to close with light thanks to the contraction of the sphincter of the pupil and to open in the dark thanks to the relaxation of that muscle by not receiving any stimulus. A light stimulus reaches the eye and in the retina it is transformed, through a chemical reaction, into an electrical stimulus that will be transmitted through the optic nerve and the visual pathways to the brain. The visual cells of the retina, rods and cones, also act as light receptors that control the pupil's motor activity. Thus, pupil-motor thresholds to light follow the same spectral sensitivity deviations as visual thresholds, which are a function of the state of light adaptation of the retina.

<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms : 
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.

Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>

Strength gains with ____ training are specific to the angle of muscle contraction.
oksano4ka [1.4K]
The answer is isometric training. To simplify, the strength gains with isometric training are specific to the angle of muscle contraction. In addition, Isometric exercise or isometrics are a kind of strong physical activity in which the joint angle and muscle length do not alter throughout contraction likened to concentric or eccentric contractions or as called as dynamic or as isotonic activities.

the tissue without using your hand to

touch the specimen?

A. Scalpel

B. Scissors

C. poker

D. T-pins

Generally Different tools have different applications to and uses during dissection.

  • Scalpel

This is a very sharp tool made of metal,Usually used to cut through specimens

  • Scissors

This a tool designed as a two metals sharpened at one end that faces each other, this tool aids in cutting

  • T-pins

This is a tool used commonly in dissections not to cut but rather to hold firmly in lace parts of specimen.This in a way stops the tool user from touching the specimen

Therefore
