Eyelids are primarily composed of skin, muscles, connective tissue, and glands. The skin on the outside of the eyelids contains hair follicles and sweat glands, while the inside of the eyelids have a mucous membrane lining. Smooth muscles called orbicularis oculi help control the movement of the eyelids.
well, you don't have to worry a penis isn't going to sprout from your eyelids. The surgeons that do this work know which skin is the best to put in what areas.
Fish don't have eyelids because they have evolved to protect their eyes using a transparent layer of tissue called the cornea. This tissue keeps their eyes moist and helps maintain their vision underwater. Eyelids would hinder their ability to see and navigate effectively in their aquatic environment.
An acrochordon is a soft wart, consisting of fibrous tissue, found on the neck or eyelids of elderly people.
Mucous tissue is the membranes that line the structures and tracts of the body. Examples of this are in the nose, stomach and intestines, urinary bladder, mouth and eyelids.
Some light is actually transmitted through the eyelid because it is a relatively thin layer of tissue. When a great amount of light illuminates your eyelids, some of it will reflect (causing its external side to appear bright) and most will be absorbed by the melanin pigment, while there tends to be a fraction that is transmitted past a cell. In thicker layers of tissue all light will eventually be stopped, but eyelids are thin and a very general color will be detected by the eye.
Bones are made of osseous tissue, ligaments are made of fibrous connective tissue, and tendons are made of dense regular connective tissue.
