Ch 15 Flashcards
Bones
Structural support and protecting of internal organs
Muscles
Internal and external movement
Joints
Where bones come come together/ type determined by need for flexibility
Tendons
Bind muscles to bones
Ligaments
Bind bones to other bones
Ossification
Replacement of cartilage with bone
Osteoblast
Produce immature bony tissue that replaces cartilage
Osteocyte
Nourishes and maintains bone
Osteoclast
Reabsorp or digest bone
Musculoskeletal system
Bones, muscles, and joints of the body
Diaphysis (bone structure)
Shaft
Epiphysis (bone structure)
End
Metaphysis (bone structure)
Flares portion between end and shaft
Epiphyseal line or plate (bone structure)
Growth plate where cartilage replaced by bone for bone growth
Compact bone
Contains haversian systems for blood vessels, nerves, and yellow bone marrow
Cancellous
Spongy trabecular bone, spaces contain red bone marrow elements for blood formation
Yellow marrow
Chiefly fat
Red marrow
Rich with blood vessels and immature and mature blood cells invarious stages of development
Bone marrow
Ribs, pelvic bone. Sternum, vertebrae, epiphyes of long bones
Processes
Deserve attachments for muscles, tendons, and ligaments
Depressions
Opening or hollow regions help join bones or serve as passageway for nerves and or vessels
Facial bones
Nasal, lacrimal, maxillary, mandibular, zygomatic, Zomer bones
Air cavities
I facial and cranial bones lighten the skull and warm and moisten the air as it passes into the respiratory system

Acetabulum
Rounded depression in pelvis that joins the femur, forming the hip joint
Acromion
Outward extension of shoulder blade forming the point of the shoulder
Articular cartilage
Thin layer of cartilage covering the bone in the joint space
Bone
Sense, hard connective tissue composing the skeleton
Bone depression
Opening or hollow region serving as a connect for bones
Calcium
A mineral constituent of bone
Cartilage
Flexible rubbery connective tissue
Collagen
Dense connective tissue protein strands found in bone and other tissues
Cranial bone
Skull bones: ethmoid, frontal, occipital, parietal, sphenoid, and temporal
