What forms the bulk of the heavily pigmented vascular layer?

The choroid plexuses form the bulk of the heavily pigmented vascular layer in the eye. This layer is richly supplied with blood vessels and helps nourish the retina. The pigment in the choroid absorbs excess light, preventing it from scattering within the eye and improving visual acuity.


Why is choroid black?

The Choroid is black because its heavily pigmented because of an excess of melanin. Also, the dark colour of the choroid prevents internal reflection in the eye, so to ensure the image received is not blurred.


What forms most of the pigmented vascular tunic?

The choroid is the layer responsible for providing the pigmentation that forms most of the pigmented vascular tunic of the eye. It helps to absorb excess light and prevent reflection within the eye, contributing to visual acuity.


What does cell division prevent the cell from becoming?

Cell division prevents the cell from becoming too large, which would hinder efficient nutrient exchange and waste removal within the cell. It also prevents the cell from becoming too damaged or dysfunctional, as dividing helps maintain genetic integrity by distributing accurate copies of DNA to daughter cells.


Succinylcholine acts as a depolarizing agent that prevents repolarization of the nerve. Name a site within the neuromuscular junction that might be affected to prevent the muscle contraction?

The nicotinic acetylcholine receptor (nAChR) on the post-synaptic muscle membrane is the site within the neuromuscular junction affected by succinylcholine. By binding to and activating these receptors, succinylcholine causes sustained depolarization and prevents repolarization, leading to muscle paralysis.

Is the ectoderm uniformly pigmented?

No, the ectoderm is not uniformly pigmented. Pigment distribution can vary within the ectoderm due to factors like genetic variation, exposure to sunlight, and presence of certain pigments like melanin.

The scattering of light by a colloid is called?

The scattering of light by a colloid is called Tyndall effect. This effect occurs when light is scattered by particles within a colloid, making the beam of light visible due to the reflection and absorption of light by the colloidal particles.

Where does coolant go?

It prevents the liquid within the engine from freezing or boiling. Coolant does just what the name implies. It keeps the engine cool, meaning it keeps the engine at the correct operating temperature. It also prevents corrosion within the engine and cooling system.
