Lacrimal glands: structures in the upper outer eye that produce
tears, lubricate the ocular surface, remove particles, and protect
against infections with substances like antibodies.
Lacrimal Sjögren’s syndrome is a pathology where the immune system
attacks the glands responsible for lubrication, reducing tear production.
This autoimmune condition causes severe ocular irritation, a foreign body
sensation, and chronic facial dryness.
Langerhans cells are immune cells in the epidermis that
capture antigens and present them to lymphocytes, triggering
immune responses and protecting the body.
The laryngeal cancer has an altered function in phonation.
Moreover, under normal conditions, vocal cords vibrate to
produce sound. Additionally, the larynx protects the airway
during swallowing.

The laryngomalacia has an altered function in respiration.
Moreover, under normal conditions, the larynx remains open.
Additionally, it allows proper airflow into the lungs.
Larynx anatomy: an organ of the respiratory system with vocal
cords, cartilages, and epiglottis that regulate airflow, produce voice,
and protect the airways.
Larynx anatomy: a cartilaginous organ in the neck that
regulates airflow, houses the vocal cords for phonation,
and protects airways through the epiglottis.
Lateral view of the vertebral column. This reveals a structure
composed of cervical (C1-C7), thoracic (T1-T12), lumbar (L1-L5),
and sacral (S1-S5) vertebrae, as well as the coccyx, which together
form the human spine. The natural curvature provides both support
and flexibility.
The prostate lies below the bladder and surrounds the urethra.
It produces prostatic fluid that forms part of semen, while the
bladder stores and expels urine in the male urinary system.
Lateral view of the brain. This anatomical representation shows
the main sulci and lobes of the nervous system. The structure
includes the frontal, parietal, temporal, and occipital sectors. Each
area manages specific processes such as memory, sensory
perception, and cognition.
