Front

What is the pigmented epithelium?

Back

The pigmented epithelium is a layer of cells in the retina that contains melanin, which helps absorb excess light and prevents scattering, playing a crucial role in visual function.

Front

What is the parathyroid gland?

Back

The parathyroid gland is a small endocrine gland located behind the thyroid gland that produces parathyroid hormone (PTH), which regulates calcium levels in the blood.

Front

What are the structures of the pharynx?

Back

The pharynx consists of three main parts: nasopharynx, oropharynx, and laryngopharynx. The oralpharynx is not a recognized structure in this context.

Front

What is the tapetum lucidum?

Back

The tapetum lucidum is a layer of tissue in the eyes of many animals that reflects light, enhancing night vision by allowing more light to reach the photoreceptors.

Front

What is the cricoid cartilage?

Back

The cricoid cartilage is a ring-shaped cartilage located in the larynx, providing support and structure to the airway and serving as an attachment point for muscles and ligaments.

Front

What is the function of the choroid layer?

Back

The choroid layer is a vascular layer of the eye that provides nourishment to the outer layers of the retina and absorbs excess light.

Front

What is the role of the ganglion cell layer in the retina?

Back

The ganglion cell layer contains the cell bodies of ganglion cells, which receive visual information from photoreceptors and transmit it to the brain via the optic nerve.

Front

What is the bipolar layer in the retina?

Back

The bipolar layer is a layer of neurons in the retina that connects photoreceptors (rods and cones) to ganglion cells, playing a key role in visual signal processing.

Front

What is the thyroid gland?

Back

The thyroid gland is an endocrine gland located in the neck that produces hormones regulating metabolism, growth, and development.

Front

What is the function of the larynx?

Back

The larynx, or voice box, is involved in sound production, protecting the trachea against food aspiration, and regulating airflow during breathing.
