What organ lies superior to the diaphragm and left of the mediastinum?

Superficial wound healing.

Cellular contact inhibition is important in this process because it prevents cells from migrating and proliferating excessively when the wound is closed. Contact inhibition is a cell property that limits the migration and proliferation of cells in crowded environments.

Choice A is wrong because sweat production does not involve contact inhibition. Sweat glands secrete sweat through ducts that open onto the skin surface.

Choice C is wrong because scoliosis development does not involve contact inhibition. Scoliosis is a condition that causes the spine to curve sideways, and it can be caused by genetic, environmental, or unknown factors.

Choice D is wrong because tyrosinase production does not involve contact inhibition.

Tyrosinase is an enzyme that catalyzes the production of melanin, a pigment that gives color to the skin, hair, and eyes.

Testosterone is an androgen, a type of sex hormone responsible for developing male characteristics, such as pubic and axillary hair, deepening of the voice, growth of the penis, and sperm production. Testosterone is produced by the testes in males and the ovaries and adrenal glands in females.

Choice A is wrong because oxytocin is a hormone that stimulates uterine contractions during labor and milk ejection during breastfeeding.

It does not affect hair growth at puberty.

Choice B is wrong because progesterone is a hormone that prepares the endometrium for implantation and maintains pregnancy.

It does not affect hair growth at puberty.

Choice C is wrong because prolactin is a hormone that stimulates milk production in the mammary glands.

It does not affect hair growth at puberty.

Eye. Aqueous humor is a clear, watery fluid that fills the anterior and posterior chambers of the eye.

It is secreted by the ciliary body and drains through the scleral venous sinus. It provides nutrients to the lens and cornea, which have no blood supply, and maintains the eye’s normal pressure and shape.

Choice A is wrong because aqueous humor is not found in the intestines.

The intestines contain digestive fluids such as bile and enzymes.

Choice B is wrong because aqueous humor is not found in the kneecap.

The kneecap contains synovial fluid, which lubricates the joint.

Choice C is wrong because aqueous humor is not found in the heart.

The heart contains blood, which circulates oxygen and nutrients throughout the body.

The malleus, incus, and stapes are the three tiny bones in the middle ear that transmit sound vibrations from the tympanic membrane (eardrum) to the oval window of the inner ear.

They are also called the auditory ossicles or ear bones.

Choice A is wrong because the nose does not contain any bones, only cartilage and soft tissue.

Choice B is wrong because the brain does not contain any bones, only neurons and glial cells.

Choice C is wrong because the throat does not contain any bones, only muscles and glands.

Choice D is right because the ear contains the malleus, incus, and stapes in its middle part. They are the smallest bones in the body and are named after their shape: malleus (hammer), incus (anvil), and stapes (stirrup).
