Explanation

The oxytocin reflex is also sometimes called the “letdown reflex” or the “milk ejection reflex”.

It is produced more quickly than prolactin.

It makes the milk that is already in the breast flow for the current feed, and helps the baby to get the milk easily.

Explanation

Facial nerve paralysis typically cannot be directly detected on a CT (computed tomography) scan.

A CT scan can help identify potential causes of facial nerve paralysis, such as tumors 

Explanation

The familial cancer syndrome that exhibits autosomal recessive inheritance among the options listed is "Fanconi's anemia."

It is a rare genetic disorder characterized by bone marrow failure and physical abnormalities.

It is inherited in an autosomal recessive pattern, which means an individual must inherit two copies of the mutated gene (one from each parent) to develop the disorder.

The other syndromes listed—ataxia telangiectasia, Bloom's syndrome, Wilson's tumor, and xeroderma pigmentosa

typically exhibit autosomal recessive or autosomal dominant inheritance patterns

Explanation

The most common cause of neonatal deaths in developing countries is "birth asphyxia."

Hypoxia is a newborn condition caused by insufficient oxygen before, during, or after birth.

It can result from various factors such as:

• prolonged labor
• placental complications
• umbilical cord problems
• maternal health issues
  

Explanation

Aphakia is defined as the "absence of the lens from its normal position."

This condition typically occurs after surgical lens removal, often due to cataract surgery.

As a result of aphakia, the eye loses its ability to focus light onto the retina properly, leading to significant refractive error and visual impairment.

Explanation

Surgery is the mainstay treatment for nasopharyngeal angiofibroma,

This tumor is a benign but locally aggressive vascular tumor that occurs predominantly in adolescent males.

Explanation

Etomidate is the imidazole derivative among the options provided.

Imidazole is a five-membered aromatic ring containing:

• two non-adjacent nitrogen atoms
• etomidate

This imidazole ring structure is in its chemical composition.

Additional information:

Thiopentone sodium and methohexitone are barbiturate derivatives, and propofol is a phenol derivative.

Explanation

The levator palpebrae superioris muscle is primarily innervated by the oculomotor nerve (cranial nerve III).

This nerve controls several muscles responsible for eye movement and eyelid elevation.

Specifically, the levator palpebrae superioris muscle lifts the upper eyelid.

Explanation

The junction of the cornea and sclera is known as the "limbus."

This region marks the transition between the transparent cornea at the front of the eye and the opaque sclera that forms the white outer layer of the eyeball.

It is an important anatomical landmark

They play a role in various eye functions, including:

• the attachment of the iris 
• the drainage of aqueous humor from the eye.
  

Explanation

"hypertension" is often referred to as the iceberg disease.

This is because hypertension often has no obvious symptoms in its early stages, earning it the nickname "the silent killer.

"Iceberg disease" is a term used to describe conditions where only a small portion of the problem is visible or apparent
