Long Bone Anatomy Quiz Flashcards
What is the Cancellous (Spongy) Bone in a long bone and where is it located?
As the name suggests, bone interior bone with a spongy appearance, surrounded with exterior compact bone. It is usually found at the ends of the bone (Epiphysis), with tiny spots all over it.
What is the Epiphysis in a long bone and where is it located?
This part simply refers to the two ends of a long bone, with the Diaphysis being between them both.
What is the Diaphysis in a long bone and where is it located?
This part simply refers to the central area part of the long bone, with the Epiphysis being the two ends at the end.
What is Articular Cartilage in a long bone and where is it located?
A thin layer of cartilage known to be slippery, smooth, and very hard. It’s the white stuff at the end of chicken bones, and makes an incline on a bone model, or can be represented as a very thin line near the spongy bone.
What is Periosteum in a long bone and where is it located?
The most exterior part of the bone, covering all parts of the bone except for articular cartilage.
What is Compact Bone in a long bone and where is it located?
Located in the Diaphysis and found under the Periosteum, this bone is very dense and covers the entire Diaphysis.
What is the Medullary Cavity in a long bone and where is it located?
Being the cavity of the Diaphysis, this part holds red marrow which grows to yellow as it ages, along with containing the nutrient artery. It is located between the yellow marrow and spongy bone.
What is Red Marrow in a long bone and where is it located?
This is a spongy consistency of red and white blood cells, infused with and eventually growing into yellow marrow over bone life.
What is Yellow Bone Marrow in a long bone and where is it located?
Located in the Medullary Cavity and being the attach point for the Nutrient Artery, this marrow is fatty connective tissue that no longer produces blood cells.
What are the Nutrient Artery/Branches in a long bone and where are they located?
Connected to the Yellow Bone Marrow within the Medullary Cavity, this is the major supplier of oxygen and nutrients to the body of the long bone.
What is the Epiphyseal Line in a long bone and where is it located?
As the name suggests, this part of a long bone serves as a primary divider between the Epiphysis and Diaphysis, striking right between the Cancellous Bone.
What are Sharpey’s Fibers in a long bone and where are they located?
It’s literally just the stretchy stuff connecting the Periosteum to the Compact Bone.
