Forced phonation: excessive voice use increases pressure
on the vocal cords, leading to fatigue, irritation, or injury,
affecting voice quality without proper vocal techniques.
Friedreich’s ataxia has an altered function in motor coordination.
Moreover, under normal conditions, the spinal cord transmits
signals efficiently. Additionally, it allows coordination between the
brain and muscles.
The frontal vertebral column highlights its crucial role as the
foundation for the mobility and stability of the human body.
It is composed of cervical (C1-C7), thoracic (T1-T12), and lumbar
(L1-L5), and sacral (S1-S5) vertebrae, as well as the coccyx.
Frontal View of the Skull. In this view, the skull reveals the complexity
of its bony structure, which forms the facial anatomy and protects the
brain. Cranial bones such as the frontal and maxillary bones define
the facial appearance.
Frontal view illustration of the brain. This shows
the right and left hemispheres, divided by the
interhemispheric fissure, a structure that separates
both halves, and allows their anatomical symmetry
to be appreciated.
Frontal view of the foot. Technical representation of the bony
structures, including phalanges, metatarsals, and tarsal bones.
The image details the organization of the talus, calcaneus, and
cuneiforms, elements that provide the necessary anatomical base
for balance and locomotion.
Frontal view of the knee. Technical illustration of the joint showing
the arrangement of the femur, tibia, fibula, and patella. The image
displays the articular surfaces and cartilage, key elements for flexion
and human locomotion in the activities of daily living.
The spinal column. It highlights its importance as a fundamental
pillar for the body’s mobility and stability. It consists of the cervical
vertebrae (C1–C7), thoracic vertebrae (T1–T12), lumbar vertebrae
(L1–L5), sacral vertebrae (S1–S5), and the coccyx.
Fungal skin infection. This schematic illustrates how fungi affect
the skin and keratinized tissues in various body areas. The content
details symptoms of itching and scaling, emphasizing the importance
of hygiene and the use of antifungals for effective management.
Gallstones are solid deposits in the gallbladder formed by cholesterol
or bilirubin. They can obstruct the bile ducts. causing pain, nausea, and
digestive problems, and in severe cases, may require surgery for treatment.
Gastrointestinal endoscopy. A medical procedure that uses an
endoscope to visualize the digestive tract in real time, allowing
the detection of ulcers, polyps, tumors, and performing biopsies,
being key for the diagnosis of digestive diseases.
Glaucoma and high eye pressure are conditions in which increased
pressure inside the eye damages the optic nerve, gradually affecting
vision. This happens when the aqueous humor does not drain properly
through the Schlemm’s canal, causing a buildup of fluid.
