Lab 4 Terms and Lesson Flashcards
What are the functions of the skeletal system as a whole?
-Support -Protection -Assistance in movement -Mineral homeostasis -Erythrocyte production -Triglyceride storage
What are the six bone classifications?
-Long bones -Short bones -Flat bones -Sesamoid -Irregular -Sutural
Define long bones
Longer than they are wide
Define short bones
Almost equal in length and width
Define flat bones
Relatively flat but may be curved
Define sesamoid bones
Develop where there is friction, tension , and or stress
Define irregular bones
Complex shape
Define sutural bones
Located between some cranial bones (formed between structures)
Examples of long bones
Humorous, femur, phalanges, many bones in our appendages
Examples of short bones
Wrist and ankle bones
Examples of flat bones
Scapula, sternum, ribs, and cranial bones
Examples of sesamoid bones
Knee cap, not born with them
Examples of irregular bones
Vertebra and facial bones
Examples of sutural bones
The bones between cranial bones. It is between bones so its a fontanel
How many bones are along the axis of the body?
80 bones
How many bones make up the appendicular skeleton?
126 bones
Define foramen
Opening through which blood vessels, nerves, or ligaments pass
Define condyle
Round prominence that articulates with another bone
Define protuberance
A blunt projection from the surrounding bone (usually larger)
Define process
A projection or outgrowth of tissue from a larger body
Define fossa
A shallow depression in a bone
Define facet
A smooth, flat, slightly concave/convex surface for articulation
Define meatus
A tube-like opening in a bine
Define head (a bone feature)
A rounded articular projection supported on the neck of a bone
