structure of the bone
What is the epiphyseal plate?
The cartilaginous material in a bone, bone growth occurs here.
What are the characteristics of a long bone? Give one example.
Length is longer than the width, makes up most of the appendicular skeleton.
Ex. Femur, Fibula, Tibia, Phalanges, Metacarpal, Ulna, Radius, Humerus
what does organic material do for the bone?
It gives the bone elasticity
What is: a hole through which blood vessels, nerves, and ligaments pass.
Foramen
What is the medullary canal?
The hollow center of the bone, containing bone marrow and passage for nutrients in the canal.
What are the characteristics of a short bone? Give an example.
They tend to have more equal dimensions of height, length and width.
Ex. Tarsals, Carpals
What counts as the Appendicular Skeleton?
The upper and lower limbs, hips (pelvis), and shoulder
What is cancellous bone made up of?
What is: A ditchlike groove containing a tendon or blood vessel
Groove
What is the difference between the Metaphysis and the Diaphysis?
The Diaphysis is the shaft of the bone while the Metaphysis is the ends.
What are the characteristics of a Flat bone? Give one example.
Ex. Cranial Bones, Scapulae, Ribs, Sternum
How many bones are in the Axial skeleton?
80 bones
What is the compact bone?
it makes up the hard dense outter shell that completely covers the bone, thinner along the ends of the bone, and thick along the shaft.
What is: a canal or tubelike opening in a bone.
Meatus
Where are the Endosteum, Periosteum, and Medullary Canal in relation to one another?
The Medullary Canal is at the center of the bone with the Endosteum wrapping around it, and the Periosteum surrounding the outside covering both of them.
What are the characteristics of a Irregular bone? Give one example.
They are a variety of mixed shapes.
Ex. Vertebrae and Sacrum
How many bones are in the Appendicular Skeleton
126 bones
How much of the bone is made out of inorganic and organic material?
It is made up of one-third organic material and two-thirds inorganic material.
What is: an air-filled cavity within a bone
Sinus
What is the difference between pressure epiphysis and traction epiphysis?
Pressure epiphysis is located at the ends of the long bones and receive pressure from the opposing bone. Traction epiphysis is where the tendons attach to the bone, subject to a pulling or traction force.
What are the characteristics of a Sesamoid bone? Give one example.
Resemble the shape of a sesame seed.
Ex. Patella
What are the functions of the skeleteton?
It gives support and shape to the body, protects vital organs, assists in movement providing a ridged structure for muscle attachment and leverage, and manufactures blood cells.
Why are bones considered organs?
They might be considered organs because they are made up of several different types of tissue and function as integral parts of the skeletal system.
What is: a hollow or depression
