What is Palpebrae?

Palpebrae comes from the Latin word Palpitare , which means "flutter". In opholemology, Palpebrae, more commonly known as lids, protective layers of the skin that surround the front surface of the eyes. Their basic function is to prevent eye injuries by entering foreign materials such as dust and debris, or attacking bright lights that could permanently destroy their eyes.

eyelids are also useful in maintaining eyes well lubricated by production and spreading tears and mucus evenly through the eyeballs. Palpebrae for each eye is composed of two eyelids: the upper eyelid that extends up from the eye towards the eyebrows, and the lower lid that descends from the eye towards the face. The lid anatomy includes important structures such as skin, hypodermis, levator palpebrae muscles, orbicularis oculi muscles, orbital septum, tarsal plates and conjunctiva.

Palpebrae skin is less than 0.04 inches (1 mm) thick, which is by far the thinnest skin in the human body. This skin contains pigment cells, sweat glands and fine chloUPky called eyelashes. These eyelashes block dirt and dust from the entrance to the eyes. Under the skin layer is underground. Unlike other parts of the body, Hypodermis Palpebrae barely contains fat, but mainly consists of free connective tissue.

There are two muscles that allow Palpebrae to maintain its Latin definition. These are Levator Palpebrae and Oculi orbicularis muscles that are responsible for opening and closing the lids. The former muscle is located deep in the eye sockets and extends through the eyeballs, where it is connected to the lids over the tendon of the levator aponeurosis, the tissue that pulls and lifts the upper cap to open their eyes. The latter muscle is all around the eyes and is the only muscle of the ThPři control of the closure of the lids. Any damage to this muscle may lead to a potential loss of the eye.

While Palpebrae protects the front surface of the eyes, the orbital septum protects their back area. The structure of connective tissue, orbital withPtum forms a layer of fat surrounding the upper and lower rims of the eyeball. It is associated with the Levator Palpebrae muscle in the upper eyelids and tarsal plates in the lower lids, which somewhat affects the movement of eyeballs.

Tarsal plates are a strong fibrous tissue that stretches over the lids, giving them a unique shape. These boards consist of two tarsi: a superior Tarsus in the upper eyelid and lower tars in the lower lid. Each Tarsus has a maximum length of about 1.14 inches (29 mm) and a width of 0.04 inches (about 1 mm). The larger of these two, bound cylinder superior to Tarsus, has a vertical height of approximately 0.4 inches (10 mm) in the center of the eye. Both of these tarsal plates contain anywhere between 20 and 50 Meibomian glands that are responsible for the spread of sebum in the eyes.

Conjuncts are a thin and clean layer of mucosa, which line the interior of Palpebrae and covers every eyeball. Its task is to produce optical fluids such as mucus andtears. When these fluids are spreading throughout the eyes, the conjunctiva prevents the entry of bacteria and foreign substances. When the eyes are exposed to very aggressive materials, red and inflamed can be conjunctivated, resulting in an eye disease called conjunctivitis or pinkeye.

In the discussion of the anatomy of the eye, Palpebrae is often defined rather simplified. Due to their protective nature, however, are the first defensive line of the eyes against any injury and bacterial infection that could permanently damage the organ organ.
