Human Bones Anatomy

Human Bones Anatomy

The human skeleton, an internal framework, is composed of individual bones and cartilages. It’s intimately associated with fibrous connective tissues, the ligaments, and tendons. The skeleton can be divided into two main parts:

1. Axial Skeleton: Comprises the vertebral column, much of the skull, and the visceral part, which includes the lower jaw, some elements of the upper jaw, and the branchial arches, including the hyoid bone.
2. Appendicular Skeleton: Includes the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs.

The skeleton performs three primary functions: support, protection, and motion. The vertebral column, corresponding to the notochord in lower organisms, is the main support of the trunk. The central nervous system lies largely within the axial skeleton, the brain being well protected by the cranium and the spinal cord by the vertebral column.

Bones are living tissues that make up the body’s skeleton. There are three types of bone tissue:

1. Compact Tissue: The harder, outer tissue of bones.
2. Cancellous Tissue: The sponge-like tissue inside bones.
3. Subchondral Tissue: The smooth tissue at the ends of bones, covered with cartilage.

The tough, thin outer membrane covering the bones is called the periosteum. Beneath the periosteum’s hard outer shell are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone. Muscles, ligaments, and tendons may attach to the periosteum.

Bones are classified by their shape—as long, short, flat, and irregular. Primarily, they are referred to as long or short. The adult human skeleton consists of 206

The Human Skeleton: A Comprehensive Overview

The human skeleton is a marvel of biological engineering, providing support, protection, and facilitating movement. It consists of 206 bones in adults, each a complex organ made up of cells, protein fibers, and minerals.
tructure and Function

Bones are organs composed of dense connective tissues, primarily the tough protein collagen. They contain blood vessels, nerves, and other tissues. Bones are hard and rigid due to deposits of calcium and other mineral salts within their living tissues. The skeletal system includes a network of tendons, ligaments, and cartilage that connect the bones together.

The skeleton acts as a scaffold, providing support and protection for the soft tissues that make up the rest of the body. It also provides attachment points for muscles to allow movements at the joints. New blood cells are produced by the red bone marrow inside our bones. Bones act as the body’s warehouse for calcium, iron, and energy in the form of fat.

Axial and Appendicular Skeleton

The human skeleton consists of two principal subdivisions:
1. Axial Skeleton: Comprising the vertebral column (the spine) and much of the skull. It also includes the hyoid bone and some elements of the upper jaw.
2. Appendicular Skeleton: Includes the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs.
kull

The skull is composed of 22 bones that are fused together except for the mandible. These 21 fused bones are separate in children to allow the skull and brain to grow, but fuse to give added strength and protection as an adult. The mandible remains as a movable jaw bone and forms the only movable joint in the skull with the temporal bone.

Vertebrae

Twenty-six vertebrae form the vertebral column of the human body. They are named by region: Cervical (neck) – 7 vertebrae, Thoracic (chest) – 12 vertebrae, Lumbar (lower back) – 5 vertebrae, Sacrum – 1 vertebra, Coccyx (tailbone) – 1 vertebra.

Conclusion

The human skeletal system is a complex structure that plays a crucial role in our daily lives. It provides the framework that allows us to

Bones Of The Foot And Ankle

The foot and ankle form a complex system which consists of 28 bones, 33 joints, 112 ligaments, controlled by 13 extrinsic and 21 intrinsic muscles?. The foot is subdivided into the rearfoot, midfoot, and forefoot?.

Ankle Anatomy

The ankle joint, also known as the talocrural joint, allows dorsiflexion and plantar flexion of the foot. It is made up of three joints: upper ankle joint (tibiotarsal), talocalcaneonavicular, and subtalar joints. The last two together are called the lower ankle joint. The upper ankle joint is formed by the inferior surfaces of tibia and fibula, and the superior surface of talus. The lower ankle joint is formed by the talus, calcaneus, and navicular bone.

Bones of the Foot

The foot begins at the lower end of the tibia and fibula, the two bones of the lower leg. At the base of those, a grouping of bones form the tarsals, which make up the ankle and upper portion of the foot. The bones of the foot are organized into the tarsal bones, metatarsal bones, and phalanges.

1. Tarsal Bones: These include the talus and calcaneus, which form the ankle joint and the heel, and the navicular, cuboid, and three cuneiforms, which form the arch of the foot.
2. Metatarsal Bones: These are the long bones that connect the tarsals to the toes.
3. Phalanges: These are the small bones that form the toes. The great toe consists of two phalanges (proximal, distal), while the remaining four toes have three phalanges (proximal, middle, distal).

Joints of the Foot

The foot has several joints, including intertarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal joints. The great toe has one interphalangeal joint, while the other four toes have two (proximal, distal) interphalangeal joints.

Muscles of the Foot

The foot has several muscles that allow movements like foot inversion, foot eversion, toe flexion, toe extension, toe abduction, and toe adduction. These include dorsal muscles (extensor digitorum brevis, extensor hallucis brevis), lateral plantar muscles (abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi), central plantar muscles (flexor digitorum brevis, quadratus plantae, lumbricals, plantar interossei, dorsal interossei), and medial plantar muscles (abductor hallucis, adductor hallucis, flexor hallucis brevis).

In conclusion, the foot and ankle’s complex structure, consisting of numerous bones, joints, and muscles, allows for a wide range of movements and provides the necessary stability and flexibility for various activities such as walking, running, and jumping..

The hip is formed where the thigh bone (femur) meets the three bones that make up the pelvis: the ilium, the pubis (pubic bone) and the ischium. These three bones converge to form the acetabulum, a deep socket on the outer edge of the pelvis. By adulthood, these three bones are completely fused and the pelvis is effectively a single bone.

Microscopic Structure of Bones. The skeleton makes up about 30-40% of an adult’s body mass. The skeleton’s mass is made up of nonliving bone matrix and many tiny bone cells. Roughly half of the bone matrix’s mass is water, while the other half is collagen protein and solid crystals of calcium carbonate and calcium phosphate.
