What supports soft tissues and provides points of attachment for the tendons of most skeletal muscles?
Skeletal system
What provides protection for the internal organs from injury?
Skeletal system
What assists in movement when muscle contraction pulls on bones?
Skeletal system

What are some examples of long bones?

What are some examples of short bones?
Almost cube shaped
Most wrist and ankle bones
What are some examples of flat bones?
Thin and extensive surface

- sternum
- ribs
- scapulae
What are some examples of irregular bones?
Do not fit in the other categories
- Vertebrae
2. Facial bones
What are the parts of a long bone?
- diaphysis
a. shaft - Epiphyses
a. ends of the long bone - Metaphyses
a. contains the “growth plate” (epiphyseal plate)
b. located between the shaft and end of bone
What are the bone building cells?
osteoblasts
What cells of the bone does the following:
- maintain bone
- exchange nutrients and waste with the blood
- these are osteablasts encased in the matrix they build
Osteocytes
What cells of the bone digest bone matrix for normal bone turnover?
Osteoclasts
What are the points of contact between bones?
Joints
Joints are classified into what based on their structure?
- fibrous
- cartilaginous
- synovial
What type of joint has no cavity and is just dense irregular connective tissue?
Fibrous joints
