The cross-section of the cochlea shows the spiral structure
of the inner ear. It contains the organ of Corti, where hair
cells transform sound vibrations into electrical signals that
allow us to perceive different frequencies and tones.
Cochlear ducts are spiral structures inside the cochlea of
the inner ear. They contain fluid and the organ of Corti,
where hair cells convert sound vibrations into electrical
signals that allow the brain to detect different sound
frequencies.
The vestibulocochlear system connects the cochlea and
the vestibular system with the brain. The cochlea processes
sound, while the vestibular system controls balance and
spatial orientation.
Cancerous colon tumor. A malignant mass that affects the intestine
thick, causing intestinal changes, rectal bleeding, and weight loss
weight, with early detection through colonoscopy being key.
Colorectal cancer. A malignant tumor that affects the colon or rectum,
altering intestinal transit and causing symptoms such as bleeding,
digestive changes and weight loss, requiring diagnosis early through
colonoscopy.
The cornea and ocular surface allow light to enter the eye
and contribute to focusing images on the retina. In addition,
the cornea protects the eye and maintains visual clarity
through its transparency and curved structure.
This anatomical illustration of a coronal section
of the brain shows the brain structure in detail.
First, it highlights key elements such as the
cortex, hypothalamus, and ventricles.
Cortisol production occurs in the adrenal cortex after
ACTH stimulation from the pituitary. It regulates
metabolism, blood pressure, and the body’s response
to stress.
