Functions of Bone and Skeletal System
This term's function serves as the structural framework for the body
-provides an attachment point for tendon and muscles
What is the support of the skeleton?
This tissue is...
- Always located in the interior of a bone, protected by a covering of compact bone tissue
- offers resistance along stress lines
- Supports and protects red bone marrow
This part of a typical long bone is a hollow, cylindrical space within the diaphysis that contains yellow bone marrow and blood vessels
What is the Medullary Cavity (Marrow Cavity)
The line that replaces the cartilage in the epiphyseal plate is replaced by bone resulting in...
What is epiphyseal line?
Within certain bones, the connective tissue called red bone marrow produces...
What are blood cells?
- red
- white
- platelets
This bone has
- greater length than width
- consist of a shaft and a variable number of extremities
- Slightly cured for strength
What are long bones?
- Humerus, ulna, radius, femur, tibia, fibula, phalanges.
This part of a typical long bone is a thin layer of hyaline cartilage covering the part of the epiphysis where the bone forms an articulation with another bone, and articulating cartilage of this part reduces friction and absorbs shock at freely movable joints
What is the Articular Cartilage
Repair of damage is limited because it lacks a perichondrium and blood vessels.
What is articular cartilage?
This skeleton "blanks" the most important internal organs from injury
What is protection?
These bones...
- are somewhat cube-shaped
- nearly equal in length and width
- Consist of spongy bone except at the surface where there is a thing layer of compact bone
What are short bones?
- Carpals (not pisiform)
- Taral (not calcaineous)
This type of a typical long bone is the bone’s shaft, and this type of bone is the proximal and distal ends of a long bone
What are (1) Diaphysis and (2) Epiphyses
These bones have...
- complex shapes
- vary in the amount of spongy and compact bone present
What are irregular bones?
- vertebrae
- calcaneus
Most skeletal muscles attach to bones; when they contract, they pull on bones to produce movement
What is assistance in movement?
This tissue is...
- found at the surface of a bone and can extend deeper into bone tissue
- consists of osteons with little spaces between them
- protects, supports, and resists stress
What is compact/cortical bone tissue?
This part of a typical long bone is a tough sheath that surrounds the bone surface wherever it is not covered by articular cartilage
What is the Periosteum
This bone...
- develops in certain tendons where there is considerable friction, compression, and physical stress
-protect tendons from excessive wear and tear
- Often change the direction of the pull of the tendon to improve the mechanical advantage of a joint
What are sesamoid bones?
- patella
99% of calcium is stored in bone tissues. Bones release minerals into blood on demand to maintain homeostasis.
What is mineral storage and release?
These bones...
- are generally thin
- composed of parallel plates of compact bone enclosing layers of spongy bone
- compact bone called external/internal tables
- sponge bone called dipole
- Afford considerable protection
- Provide muscle attachment areas
What are flat bones?
- Cranial, sternum/ribs, scapula
This part of a typical long bone is a thin membrane that lines the medullary cavity
What is the Endosteum
This bone...
- has small bones located within the suture (points) of certain cranial bones
- the quantity varies greatly from person to person
What are sutural bones?
