The third form of tear, also known as the basal tear, is a type of tear secreted by the lacrimal gland, a gland located in the outer corner of the eye. These tears serve a vital role in maintaining the health and function of the eye.
Basal tears are constantly secreted in small amounts, even when we are not crying or experiencing any physical or emotional discomfort. They help to lubricate the eye, keeping it moist and comfortable. They also contain enzymes and other substances that help to protect the eye from infection and inflammation.
One of the main components of basal tears is mucin, a glycoprotein that helps to coat the surface of the eye and keep it smooth. Mucin helps to prevent the eye from drying out and becoming uncomfortable, and it also helps to keep foreign particles from entering the eye.
In addition to mucin, basal tears also contain a variety of other substances, including electrolytes, proteins, and antioxidants. These substances help to keep the eye healthy and functioning properly, and they also help to repair any damage that may occur to the eye.
While basal tears are essential for maintaining the health of the eye, they are not always sufficient to fully lubricate and protect the eye. In times of stress or emotion, the body may produce additional tears, known as reflex tears, to help wash away any foreign particles or irritants that may have entered the eye.
In conclusion, the third form of tear, or basal tear, is a vital component of eye health. It helps to lubricate and protect the eye, and it contains a variety of substances that keep the eye healthy and functioning properly. Without basal tears, the eye would be prone to dryness, discomfort, and infection.

First-Degree Lacerations First-degree lacerations are normally superficial lacerations that have minimal bleeding. For example, when the baby's head reaches the perineum there is a surge of the hormone oxytocin, which helps to maintain contractions. Also called a perineal laceration, this is a tear in the tissue skin and muscle around your vagina and perineum. Tears cannot always be avoided, but the extent of the damage can often be minimised by the skill of the midwife. Use of forceps and vacuum extraction If the mother has been in the second stage for a long time and is becoming exhausted, forceps may be used to lift the baby out. They are likely to be missed unless the perineum is carefully examined by a senior obstetrician Keighley et al, 2000; Groom and Patterson-Brown, 2000. This allows your doctor to confirm that the anal muscles have healed together adequately.

Moreover, it may be difficult for the patient to flex the knee due to pain. You will also have the opportunity to discuss your delivery and ask any questions. Third-Degree Lacerations Third-degree tears extend through the skin, mucous membranes, and perineal body, and involve fibers of the rectal sphincter. We spent consider'ble money getting 'em reset, and then a swordfish got into the pound and tore the nets all to slathers, right in the middle of the squiteague season. Reasons why tearing might occur First, the baby may be large; the baby's face might touch the perineum first instead of the back of its head, causing a tear. The diagnosis of a 3a, 3b or 3c tear is very important to the repair, as the surgeon will know exactly how much of the sphincter needs to be sutured. For an elective caesarean section see Ch.
