Functions of the bone and the Skeletal System

Question 1

What is the Skeletal System consist of?

Answer 1

The Skeletal System is made up of Bone(Osseous) Tissue, Cartilage, Dense connective tissue, Epithelium, Adipose and Nervous tissue.

Question 2

What are the 6 basic functions of the Skeletal System?

Answer 2

This includes Support, Protection, Assistance in movement, Mineral Homeostasis, Blood cell production and Triglyceride Storage(yellow Bone Marrow).

Question 3

What does the Structure of the bone include?

Answer 3

Most long bones consist of the following…

Diaphysis, Epiphysis, Metaphyses, Articular Cartilage, Periosteum, Medullary Cavity.

Question 4

What is the Process called Hemopoiesis?

Answer 4

This is the action of bone marrow creating different types of material…
Red/White blood cells and Platelets.

Question 5

What is the Diaphysis?

Answer 5

The Diaphysis is the Long cylindrical portion of the bones shaft.
The main portion.

Question 6

What is the Epiphysis?

Answer 6

This is the Proximal and Distal ends of the bone?

Question 7

What is Metaphyses?

Answer 7

This is The portion of the bone between the Diaphysis and the Epiphysis.
It contains a layer of Hyaline Cartilage that allows for the Diaphysis to grow in length.

Question 8

What is Articular Cartilage?

Answer 8

This is a thin layer of Hyaline Cartilage that covers the Epiphysis where the bone creates a (Joint).
This helps absorb shock and reduce friction of the bones at the joint.
Because Articular cartilage dose not contain a Periosteum and lacks blood vesicles repair of this tissue is limited.

Question 9

What is the Periosteum?

Answer 9

This is a layer of tough connective tissue sheath and is associated with blood supply that surrounds the bones surface wherever isn’t covered with Articular cartilage.
This is where tendons can insert to the bone.
It also helps in tissue repair and is held to the bone by Perforating Fibers.

Question 10

What is the Medullary Cavity?

Answer 10

This is the hollow space within the Diaphysis. It helps reduce weight while keeping a Strong structure. This is where yellow bone marrow is held.

Question 11

What is Triglyceride Storage?

Answer 11

This is Yellow bone Marrow and it is used for storing triglycerides as potential energy reserves.
