Question

State the function of: [5]
1. Tears
2. Oxytocin
3. Eustachian tube
4. Vitreous humour
5. Corpus callosum

Answer 1

Answer:

1-The function of tears is to lubricate the surface of eyes and kill germs

2- is a birth hormone. controls vigorous contractions of the uterus

3- equalises pressure on either side of the ear drum allowing to to vibrate freely

4- to keep the shape of the eyeball and protect optic nerve

5- transfers information from one cerebral hemisphere to another hemisphere

Answer 2

Explanation:

1. After blinking, a film of tear fluid coats the surface of the eye at a certain thickness, and is maintained for a while. This is called tear stability. Tears not only keep the eye moist but also have an important role in maintaining the healthy functioning of the eye.
2. Oxytocin has been best known for its roles in female reproduction. It is released in large amounts during labor, and after stimulation of the nipples. It is a facilitator for childbirth and breastfeeding.
3. An air-containing middle ear is necessary for normal hearing, both because it allows free vibration of the eardrum and ossicles so that sound pressure can be transmitted to the inner ear fluid and because it affords protection from sound to the round window. This air-containing space is maintained by the Eustachian tube, which opens intermittently to equalize the intratympanic air pressure with the pressure in the external auditory canal. It also removes secretion and epithelial debris from the middle ear by ciliary motion and gravity.

4. Gel-like fluids inside the eye help it maintain its shape, which plays an important role in overall eye health. These substances are called the vitreous humor and aqueous humor.

Vitreous is a transparent substance that is around 99 percent water. The remaining one percent is collagen and hyaluronic acid, which cause vitreous to have a gelatinous consistency. Along with maintaining the shape of the eye, the vitreous helps absorb shocks to the eye and keeps the retina properly connected to the back wall of the eye. Light passes through the vitreous on its way to the retina.

5. The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other.
