Question

bone internal features
internal feature
function (what it does / it’s job in the bone)
location (where you find it on the bone) describe and sketch
compact (cortical) bone
spongy (cancellous) bone
periosteum
medullary cavity
red bone marrow
yellow bone marrow
blood vessel

Explanation:

• Compact (cortical) bone: Provides strength and structure. Located on the outer - layer of bones.
• Spongy (cancellous) bone: Lighter, contains red marrow in some bones, provides some shock - absorption. Found at the ends of long bones and in the interior of other bones.
• Periosteum: A fibrous membrane, helps in bone growth, repair, and attachment of muscles and tendons. Covers the outer surface of bones (except at joints).
• Medullary cavity: Holds yellow bone marrow in adults, provides space within the bone. In the center of long bones.
• Red bone marrow: Produces blood cells (erythrocytes, leukocytes, and platelets). Found in spongy bone of flat bones like the sternum and in the epiphyses of long bones in children.
• Yellow bone marrow: Stores fat, can convert to red marrow in certain conditions. In the medullary cavity of long bones in adults.
• Blood vessel: Supplies nutrients and oxygen to bone cells, removes waste. Runs through canals in bone and to the marrow.

Answer:

Internal Feature	Function (what it does / it’s job in the bone)	Location (where you find it on the bone)
Spongy (cancellous) bone	Lighter, shock - absorption, contains red marrow in some	Ends of long bones, interior of other bones
Periosteum	Aids in bone growth, repair, muscle/tendon attachment	Covers outer surface of bones (except joints)
Medullary cavity	Holds yellow bone marrow in adults	Center of long bones
Red bone marrow	Produces blood cells	Spongy bone of flat bones, epiphyses of long bones in children
Yellow bone marrow	Stores fat, can convert to red marrow	Medullary cavity of long bones in adults
Blood vessel	Supplies nutrients/oxygen, removes waste	Runs through canals in bone and to the marrow
