This type of cell is critical in the regeneration of bone through bone remodeling by absorbing bone tissue where it is not needed or is degenerating
What are Osteoclasts?
The connective tissue that attaches bone to bone
Ligaments
This muscle classification describes the muscle most responsible for producing a certain movement
Prime movers
List 3 functions of the muscular system
Movement, maintain posture, stabilize joints, generate heat, guards entrances/exits
This is the name for the movable bone during a muscle contraction
Insertion point
List the 4 bone classifications
This type of joint connects bones with dense connective tissues and a fluid filled joint cavity
Synovial Joints
List the 3 types of muscle tissue
Cardiac, Smooth, Skeletal
List the 3 structural types of joints
This type of contraction causes a change in the length of the muscle
Isotonic
This is the basis structural unit of bone. Seen in compact bone only.
What are osteons
List 4 of the 6 synovial joint configurations (types of movements)
This organelle makes up most of the muscle cells
Myofibrils
List 4 of the 6 functions of the skeletal system
Support, Protection, Movement, Storage, Blood Cell Formation, Hormone Production
This is how long bone repair can take
4 months - 1 year
This section of bone have trabeculae, which help the bone resist stress. This section also houses the bone marrow
What is the spongy bone?
This structural classification connects bone with cartilage. It can be rigid but is slightly movable
Cartilaginous joint
This activates/stimulates muscle contractions
Somatic motor neurons in the nervous system
List 3 of the 6 special features of synovial joints
1. Articular cartilage
2. Joint Cavity
3. Joint capsule
4. Synovial fluid
5. Ligaments
6. Sensory nerve fibers/blood vessels
Muscle fibers bundle together to form __________. The ________ are bundled together to form the muscle organ.
Fascicles
Define ossification. What is the difference between intramembranous ossification and endochondral ossification?
Ossification: The process of bone tissue formation
Intramembranous - bone develops from a fibrous membrane
Endochondral - Bone develops by replacing cartilage
List the 3 functional classifications and state how much movement they allow
Synarthroses: No movement
Amphiarthroses: Slight movement
Diarthroses: Freely moving
Define "Sarcomere". What are the two types of filaments?
List the 3 types of connective tissue that wraps around different parts of the muscle to support it
1. Epimysium - wraps around entire outside of muscle
2. Perimysium: Surrounds each fascicle
3. Endomysium: Surrounds each muscle fiber
Give an example of a fibrous joint
Syndesmoses between fibula and tibia in lower leg
The way teeth are embedded in sockets (gomphoses)
