Anatomy and Physiology: Skeletal System

Vocabulary flashcards covering key concepts from Anatomy and Physiology regarding the skeletal system.

Skeletal Cartilage

A type of cartilage found in the skeletal system, important for the structure, function, and location in the human skeleton.

Ossification

The process of bone formation.

Haversian System

Also known as Osteon, it is the structural unit of compact bone.

Osteoblasts

Bone-forming cells that are responsible for the synthesis and mineralization of bone during bone formation.

Osteocytes

Mature bone cells that maintain bone tissue.

Parathyroid Hormone

Hormone that regulates calcium levels in the blood and bone remodeling.

Calcitonin

Hormone released by the thyroid that lowers blood calcium levels by inhibiting osteoclast activity.

Bone Resorption

The process by which bone is broken down and minerals released into the bloodstream.

Mechanical Stress

Physical stress applied to bones that can influence their remodeling and growth.

Fractures

Breaks in bones that can be classified based on their nature and severity.

Closed Reduction

A procedure to set a fracture without surgery.

Open Reduction

A surgical procedure to align fractured bones.

Interstitial Lamellae

Lamellae that fill the gaps between osteons in compact bone.

Circumferential Lamellae

Lamellae that lie on the outer and inner circumference of the bone.

Osteomalacia

Softening of the bones due to vitamin D deficiency.

Osteoporosis

A condition characterized by reduced bone density, leading to an increased risk of fractures.

Paget’s Disease

A chronic disorder that can result in enlarged and misshapen bones.

Hematopoietic Tissue

Tissue involved in the production of blood cells, typically found in the bone marrow.

Diaphysis

The main or central shaft of a long bone.

Epiphysis

The end part of a long bone, initially growing separately from the shaft.

Fat Storage in Bones

The role of bones in storing adipose tissue, which serves as an energy reserve.
