Lens extraction in cataracts is a surgical procedure used
in advanced cases. This representation shows the cornea,
lens, aqueous humor, retina, and optic nerve.
The crystalline lens is a transparent and flexible structure
located behind the iris that focuses light onto the retina.
Through accommodation, controlled by the ciliary muscles,
the lens changes shape to focus on objects at different
distances.
The lens replacement in cataract surgery illustrates the final stage,
where the cloudy lens is replaced with an artificial intraocular lens.
After removing the lens using phacoemulsification, the new lens is
implanted through a small incision in the cornea.
The limbic structures of the brain are composed
of several interconnected regions that regulate
emotions, memory, and behavior. First, they
include the hippocampus, which is essential
for memory and learning.
The limbic system is a group of brain structures that
regulates emotions, memory, and behavior. First, this
system includes regions such as the hippocampus,
the amygdala, and the hypothalamus.
Limbic system anatomy comprises a set of brain

Lips in Sjögren’s syndrome describe the extreme dryness and cracking
caused by the immune system’s attack on the salivary glands. This
condition reduces saliva production, affecting lip flexibility and causing
persistent facial irritation.
Lobular breast cancer. A tumor that originates in the lobules and
may not form lumps, making detection difficult. Includes forms
in situ and invasive, with a risk of dissemination and the need for
early diagnosis.
Stages of mammary lobules. Comparison between healthy
lobe and affected by carcinoma, showing structural changes,
abnormal cell proliferation and alteration of function
