• cornea

• limbo

• iris

An electron micrograph reveals a retinal cell in which one of the processes has a segment with half-disks. What is the pigment found in the membranes of these half-disks?

• iodopsin

• rhodopsin

• melanin

• hemosiderin

The electronic micrograph shows a cell of neural origin located in the epithelium of the mucous membrane. The distal part of the peripheral process of the cell has a club-shaped thickening, from which 10-12 cilia depart. What kind of cage is this?

• cone visual cell

• rod-shaped visual cell

• olfactory cell

• sensory cell of the taste bulb

The structure of olfactory receptor cells are:

• Unipolar neurons

• Bipolar neurons

• Multipolar neurons

• Pseudounipolar neurons

Layer of the retina, consisting of a nucleated parts of the photoreceptor cells:

• outer nuclear

• rodes and cones

• inner nuclear

• ganglionic

Bipolar retinal neurocytes:

• connect theamacrine cells with ganglion cells

• connect the photoreceptor cells with horizontal

• their axons form a layer of nerve fibers

• connect the photoreceptor cells with ganglion cells

The patient's ciliary body is damaged. The function of which eye apparatus is affected?

• Photoconductive

• Accommodative 

• Photosensitive

• Protective

The boxer after the injury of the nose there is a violation of smell. Identify cells whose damage can lead to loss of smell.

• Supporting epithelial cells

• Neurosensory cells 

• Basal epithelial cells

• Ciliated epithelial cells

The patient developed clouding of the lens, or cataract. With violation of what structure of a lens it is connected first of all?

• The lens fibers 

• Lens epithelium

• The nucleus of the lens

• Capsule of the lens
