Members of the deer family (Cervidae) are cloven-hoofed ungulates that typically have compact torsos with long, slender legs and small tails — and most males have antlers. The family is quite large, and includes caribou, elk, moose, muntjacs and wapiti.
A small wingless bloodsucking insect that, along with the mite, belongs to the order Acarina. Ticks may be found in tall grass, where they may attach to a passing animal or person. Pulling a tick forcefully out from under the skin may leave the head behind.
When you shine a light into one pupil, the normal reaction of the other pupil should be to become smaller.
Penlight
The most popular tool for measuring pupil diameter now has a light source and is a penlight. One pupil contracts in reaction to light, whereas the other either doesn't contract at all or contracts more slowly.
Use a penlight to get the maximum amount of pupil contraction in one eye, then quickly move to the other eye and return to the first. A consensual reaction normally causes the second eye to respond with the same pupillary constriction as the first.
Penlight is a useful examination tool for doctors, particularly for small body parts like the mouth, nose, ears, and eyes. They frequently employ it for the pupil test, a physical examination technique used to determine whether pupils contract or remain dilated in response to light.
