Explanation

Malabsorption due to a mucosal intestinal defect is commonly associated with celiac disease.

Even though celiac disease typically damages the upper part of the small intestine (duodenum), the entire small bowel can be affected.

This damage results in malabsorption of nutrients, leading to symptoms such as diarrhea, weight loss, fatigue, and deficiencies in vitamins and minerals.

Explanation

The cells contained in the lacunae of the bone are called osteocytes.

Explanation

The diffusion of sodium ions across the postsynaptic membrane causes it to depolarize, initiating a new action potential.

Explanation

• Pulmonary veins are the only veins that transport oxygenated blood to the heart.
• Specifically from the lungs to the left atrium.

Explanation

• The iris is the colored part of the eye that surrounds the pupil.
• It controls the amount of light entering the eye by adjusting the size of the pupil.

Explanation

Fluorescent microscopy is not typically used for the direct detection of serum autoantibodies.

Instead, techniques such as enzyme-linked immunosorbent assay (ELISA) or immunofluorescence assays (IFA) using serum samples are more commonly employed.

Fluorescent microscopy is used for various purposes in medicine, particularly in the diagnosis and study of diseases.

Explanation

Chlamydial infection, especially if it leads to inflammation or scarring of the fallopian tubes, increases the risk of an ectopic pregnancy.

This is because the scarring or damage to the fallopian tubes can hinder the normal passage of a fertilized egg from the fallopian tube to the uterus

Leading to the implantation of the embryo outside of the uterus

Typically in the fallopian tube (which is characteristic of ectopic pregnancy).

*

The other options listed do not directly increase the risk of ectopic pregnancy.
