Which hormone is produced by the posterior pituitary gland?

Fallopian tubes. Fertilization of an ovum usually takes place in the uterine tube, also known as the fallopian tube. This is the structure that transports the ovum from the ovary to the uterus.

Choice A is wrong because the cervix is the lower part of the uterus that connects to the vagina. It does not receive or transport the ovum.

Choice C is wrong because the ovaries are the organs that produce and release the ova. They do not host the fertilization process.

Choice D is wrong because the horn of the uterus is the point where the uterine tube joins the uterus. It is not the site of fertilization.

The normal range of temperature for human body is 36.5–37.5 °C (97.7–99.5 °F).

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).

Vena cava. The vena cava is a large vein that carries blood from the body to the heart. It has two branches: the superior vena cava and the inferior vena cava, which drain blood from the upper and lower half of the body respectively.

Choice A is wrong because the jugular vein is a vein that drains blood from the head and neck.

It is not the vessel that carries blood from the whole body to the heart.

Choice C is wrong because the hepatic vein is a vein that drains blood from the liver.

It is not the vessel that carries blood from the whole body to the heart.

Choice D is wrong because the femoral vein is a vein that runs along the thigh and drains blood from the lower limb.

It is not the vessel that carries blood from the whole body to the heart.

Carotid artery.

The carotid artery is a major blood vessel that supplies blood to the head and neck. It can be felt as a pulse on either side of the neck, just below the jawline.

Choice A is wrong because the subclavian artery is located below the clavicle (collarbone) and cannot be felt as a pulse on the neck.

Choice C is wrong because the brachiocephalic artery is a large vessel that branches into the right subclavian and right carotid arteries. It is located deep in the chest and cannot be felt as a pulse on the neck.

Choice D is wrong because the basilar artery is a vessel that forms at the base of the brain from the union of the two vertebral arteries. It cannot be felt as a pulse on the neck.

The normal range for pulse rate in adults is 60 to 100 beats per minute.
