Lateral view of the foot. Illustration of the bony anatomy showing
the connection of the tibia and fibula with the talus and calcaneus.
The image details the tarsal bones, such as the navicular and cuboid,
essential for maintaining balance, arch structure, and human mobility.
Lateral view of the knee. This anatomical perspective details the
relationship between the femur, tibia, and patella. The illustration
highlights the articular surfaces and cartilages that allow for flexion
and extension of the leg, being fundamental for understanding
locomotion and skeletal stability.
Lateral view of the spine. It shows the segmented structure of the
vertebrae that make up the human back. It consists of cervical
vertebrae (C1–C7), thoracic vertebrae (T1–T12), lumbar vertebrae
(L1–L5), sacral vertebrae (S1–S5), and the coccyx. Its natural
curvature provides support and flexibility.
Human skin is composed of epidermis, dermis, and hypodermis.
These layers protect against pathogens, regulate temperature,
and enable sensory perception through melanin, vessels, and skin
appendages.
The bladder wall consists of mucosa, submucosa, detrusor
muscle, and serosa. These layers allow expansion, storage,
and contraction of the bladder during urination.
The layers of the digestive tract include mucosa, submucosa, muscular layer, and serosa. These structures support digestion, enzyme secretion, nutrient absorption, and movement of food through the system.
The left atrial appendage has a general function related to atrial
dynamics. Moreover, under normal conditions, it contributes to
left atrial contraction. Additionally, it may act as a blood reservoir.
The left atrial appendage closure has a general preventive
function in the cardiovascular system. Moreover, under normal
conditions, the appendage contributes to atrial dynamics.
Additionally, it may act as a blood reservoir.

Leg with varicose veins shows dilated and twisted veins caused
by venous valve failure, leading to blood pooling, pain, swelling,
and visible skin changes.
Legs affected by varicose veins show dilated, twisted veins caused
by venous insufficiency, leading to pain, swelling, and heaviness,
with potential complications if untreated.
The legs in Parkinson’s disease have an altered function in mobility.
Moreover, under normal conditions, dopamine regulates voluntary
movements. Additionally, it allows smooth and coordinated execution.
