Photoreceptors in the retina include cones and rods. Cones
enable detailed color vision in bright light, while rods provide
sensitivity to dim light and support peripheral vision.
Aqueous humor physiology explains how this fluid nourishes
the cornea and lens while maintaining intraocular pressure
through circulation and drainage.
The physiology of female breasts explains how breast tissues function. It includes mammary glands, lactiferous ducts, and adipose tissue, structures responsible for milk production and transport during breastfeeding.
The physiology of the cochlea explains how sound
vibrations become electrical signals. In the organ of
Corti, hair cells detect vibrations and send impulses
through the auditory nerve to the brain for sound
interpretation.
In frontal lobe physiology, we will see that it is one of
the most important regions of the human brain and
plays a fundamental role in numerous cognitive and
motor functions.
The physiology of the heart explains how blood circulates
through the body. Deoxygenated blood travels to the lungs
for oxygenation, then oxygenated blood returns to the heart
and is pumped through the aorta to supply tissues.
Molars have a multilayer structure including enamel,
dentin and pulp. Their crowns grind food while roots
anchor the tooth to the jaw through the periodontal
ligament.
The physiology of the visual system explains how the eye, The
optic nerve and the brain work together to convert light into
nerve signals that allow humans to perceive images and
interpret the visual world.
Visual physiology explains how the eye captures light and
converts it into nerve signals processed by the brain. This
process includes focusing light on the retina, transmitting
signals through the optic nerve and perceiving color, contrast
and brightness.
The optic nerve carries visual signals from the retina to
the brain. These electrical impulses are processed in the
visual cortex, allowing the brain to interpret light, color,
and shapes as visual images.
Piedraia hortae infection is a superficial fungal condition causing
dark, hard nodules on the hair shaft. Moreover, it mainly affects the
scalp and may lead to hair fragility without significant inflammation.
