What is the acetabulum?
The bony socket in the hip bone that holds the head of the femur
The term comes from the Latin word for vinegar because it resembles the base of a vinegar cruet.
Define articulation.
A joint (adjective: articular)
atlas
The first cervical vertebra
What is the axis
The second cervical vertebra
What is bone?
A calcified form of dense connective tissue; osseous tissue; also an individual unit of the skeleton made of such tissue (root: oste/o)
What is bone marrow?
The soft material that fills bone cavities; yellow marrow fills the central cavity of long bones; blood cells are formed in red bone marrow, located in spongy bone tissue (root: myelo)
What is a bursa?
A fluid-filled sac that reduces friction near a joint (root: burs/o)
Define cartilage.
A type of dense connective tissue found in the skeleton, larynx, trachea, and bronchi; it is the precursor to most bone tissue (root: chondr/o)
What is diarthrosis?
A freely movable joint; also called a synovial joint (adjective: diarthrotic)
What is the diaphysis?
The shaft of a long bone
The diaphysis is the long central part of a long bone.
What is the epiphyseal plate?
The growth region of a long bone located in the metaphysis, between the diaphysis and epiphysis
This area appears as the epiphyseal line when bone growth ceases.
Define epiphysis.
The irregularly shaped end of a long bone
The epiphysis is the part of the bone that articulates with other bones.
What is the ilium?
The large, flared, superior portion of the pelvic bone
The ilium is one of the three bones that compose the os coxae.
What is a joint?
The junction between two bones; articulation
Joints are crucial for movement and stability in the skeleton.
What is a ligament?
A strong band of connective tissue that joins one bone to another
Ligaments provide stability to joints.
Define metaphysis.
The region of a long bone between the diaphysis and epiphysis
This area is the growing region during development.
What is ossification?
The formation of bone tissue
Ossification is a critical process in bone development and growth.
What is an osteoblast?
A cell that produces bone tissue
Osteoblasts are essential for bone formation.
What is an osteoclast?
A cell that destroys bone tissue
Osteoclasts play a role in the resorption of bone.
Define osteocyte.
A mature bone cell that nourishes and maintains bone tissue
Osteocytes are crucial for the health of bone tissue.
What is the pelvis?
The large ring of bone at the inferior trunk formed of the two hip bones joined to the sacrum and coccyx
Each os coxae is formed of the ilium, ischium, and pubis.
What is the periosteum?
The fibrous membrane that covers a bone’s surface
The periosteum is involved in the growth and repair of bones.
What does resorption refer to in the context of bone?
Removal of bone by breakdown and absorption into the circulation
Resorption is a normal process that maintains bone health.
What is the skeleton?
The body’s bony framework, consisting of 206 bones
The axial skeleton has 80 bones, while the appendicular skeleton has 126 bones.
