Skeletal
Tissue
Tissue
Name one type of tissue that makes up the skeletal system.
Cartilage
Bone
Ligaments
Name a bone cell and its function.
Osteocytes-mature cells;regulation, communication
Osteoblast- build bone
Osteoclast- break down bone
These cube-shaped bones provide stability and limited movement
Short bones. Wrist/ankles
What are the three joint classifications?
1. Cartilaginous
2. Fibrous
3. Synovial
This skeleton includes the skull, vertebral column, and rib cage.
axial skeleton
Define ossification.
formation of new bone
What is the name for the head of the long bone?
epiphysis
These thin, broad bones protect organs and allow muscle attachment
Flat bones; skull, ribs, sternum
your hip and shoulder are what type of synovial joint?
Ball-and-socket
This skeleton includes the arms, legs, and girdles
appendicular skeleton
What is the tough connective tissue that connects bones to other bones?
Ligaments
The structural unit of compact bone made of concentric rings of matrix.
Osteon / Haversian system
Phalange bones are what shape?
Long
The knee and elbow are examples of this type of synovial joint that allows movement in one direction.
Hinge joint
How are the function of the axial and appendicular skeleton different
Axial:support and structure
Appendicular: movement/ flexibility
What are the two types of bone tissue?
Cortical- dense, compact
Cancellous-spongy
The small spaces between bone layers that house osteocytes
Lacuna
Give an example of an irregular bone.
Vertebrae Mandible
Sacrum Coccyx
Hyoid Ilium Ischium Pubis
The synovial joint type that allows sliding or gliding movements
Plane joint
What bones make up the pectoral girdle?
Clavicle and scapula
Name a type of cartilage and its location.
Fibrocartilage- between vertebrae
Elastic-ears
Hyaline- most abundant (between joints, nose, trachea, rib cage)
Define endochondral ossification and intramembranous ossification
The process where cartilage is replaced by bone during development
bone formation without cartilage
Define Sesamoid bone.
bone embedded in tendons, acts like a pulley to increase leverage/mobility
The wrist joint, which allows bending and circular motion but not full rotation, is this type.
condyloid/ellipsoid joint
What bones make up the Pelvic girdle
Ilium, Ischium, Pubis, sacrum, coccyx
