Anatomy of the femur bone. The longest and strongest bone in
the body is located between the hip and the knee. Its structure,
composed of head, neck, and shaft, facilitates body weight support
and musculoskeletal mobility through its connection with the pelvis
and the tibia.
Anatomy of the humerus, shown in three views. It extends from the
shoulder to the elbow. It consists of the head, neck, and shaft.
It articulates with the scapula at the shoulder and with the ulna and
radius at the elbow, allowing for a wide range of arm movements.

Structure of articular cartilage. It is a strong and elastic connective
tissue that covers the articular surfaces of bones in joints. It consists
of chondrocytes and extracellular matrix, providing cushioning and
facilitating smooth gliding of the joints.
The ossicles of the middle ear. Also known as auditory ossicles,
these are three small bones in the middle ear: the malleus,
incus, and stapes. These bones transmit vibrations from the
eardrum to the inner ear, facilitating hearing.
Bone anatomy of the hand. This image shows both the palm and
the back of the hand. It illustrates the complex bone structure,
which includes the metacarpals, phalanges, and carpal bones. The
metacarpals form the base of the fingers, while the phalanges
make up the fingers themselves.
Bone growth. This dynamic, regulated process in which bones
increase in length and thickness. In the growth zones, known as
growth plates or epiphyses, cartilage cells divide and transform
into bone tissue.
Bone marrow hematopoiesis. The vital process of blood cell
formation in the bone marrow. This soft tissue, located inside
the bones, produces stem cells that differentiate into red blood
cells, white blood cells, and platelets.
The lateral views of the cervical vertebrae highlight the seven
bony structures in the neck region, numbered C1 through C7. The
natural curves of the spine and anatomical features such as the
vertebral bodies, neural arches, and spinous processes are visible.
Posterior view of the cervical vertebrae. These are the
bony structures in the neck region of the spine. They are
located at the back of the neck and consist of seven
vertebrae numbered C1 through C7.
Cervical vertebrae in frontal view. The seven vertebrae that
make up the cervical region of the spine are shown. Numbered
C1 through C7, these bony structures form the neck, providing
support and flexibility.
The clavicle. Also known as the collarbone, it is a long, slender
bone that connects the scapula to the sternum. It is located in
the upper part of the thorax and forms part of the appendicular
skeleton.
