Patella functions

Patella functions & Structure

The patella, also known as the kneecap, is a thick, round, triangular bone that connects to the femur and covers and protects the anterior joint surface of the knee joint.   Patella can be found in many quadrupeds, such as mice, cats, and birds, but not in whales or most reptiles. In humans, the kneecap […]

meninges layers

Meninges Layers & Cerebra-Spinal Fluid

The meninges are three layers of protective tissue called the hard tire, the arachnoid fabric and the bulb surrounding the neuraxis. The brain and spinal cord tones are continuous, connected by magnum foramen.   Meninges layers Dura Mater The dura mater is the highest layer of the meninges layers. Its name means “hard mother” in […]

vitreous humor function

vitreous humor function & Glass cell detachment

Light enters the eye through the cornea, pupil, and lens and is then transmitted through the vitreous to the retina. Fills the space between the lens and the retina (80% of the volume of the eyeball), which lined the back of the eye and helps to keep the retina in place, pushing it to the […]

Pupil function

Pupil function & Controlling the pupil

The pupil of the eye is a black circle in the middle of the iris. Iris is a colorful ring in the eye with color and structure unique to each person. From the outside of the eye, the light passes through the transparent lens and then through the pupil. When the light reaches the tissues […]

fovea function

fovea function & Entoptic effects in the hole

The fovea is the central part of the retina, which contains only cones (zone free of rods). Creates a site that provides the sharpest image and the largest color discrimination. It is in the middle of a yellow spot.   Fovea function   Illustration of the distribution of conical cells in the central well of […]

ganglion cells function

Ganglion cells function & Distribution of retinal ganglion cells

¬†ganglion cells and their support cells contain the optic nerve. The optic nerve receives a visual signal in orbit and moves back and forth through the visual channel. Then it leads to fiber. At this point, the fibers from the temporal fields are broken up. The fibers then pass through optical paths. Most of the […]

Pia mater function

Pia mater function & Permeability

Pia mater often referred to simply as pia, is a delicate inner layer of tires, membranes that surround the brain and spinal cord. Pia mater is a medieval Latin meaning “delicate mother.”¬† The other two membrane membranes are the hard tire and the arachnoid. Both pia and spider veins are derivatives of the neural crest, […]

Primary visual cortex functions

Primary visual cortex functions & V1 neurons

The primary visual cortex is the most studied area of vision in the brain. In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical field of view. It is highly specialized in processing information about static and moving objects and is perfectly suited for pattern recognition. […]

Optic nerve function

Optic nerve function & Structure

The optic nerve is located in the back of the eye. It is also called the second cranial nerve. This is the second of several cranial nerve pairs. The task of the optic nerve is to transmit visual information from the retina to the brain’s viewing centers by means of electrical impulses.   Optic nerve […]

Hair follicle infection

Hair follicle infection symptoms and their types

Inflammation of the hair follicles is a frequent condition of the skin in which inflammation of the hair follicle occurs. This is usually caused by a bacterial or fungal infection. In the beginning, it may look like small red protuberances or white pimples around the hair follicles – tiny pockets from which hair grows. The […]
