What is the role of the skeletal system in the formation of blood cells?
To produce blood cells
Which function of the skeletal system is essential for protecting internal organs?
Protection
What is the skeletal system's role in providing structural support for the body?
To provide a framework for the body
The skeletal system is responsible for the production of white blood cells.
False
The skeletal system provides support for the muscles during movement.
True
The skeletal system is the only system in the body responsible for storing minerals.
False
The skeletal system provides protection for the internal organs through the use of muscles.
False
The skeletal system plays a role in the movement of the body through the use of leverage.
True
Functions of the Skeletal System Functions of the Skeletal System provides a strong frame that supports the body and gives it it’s shape
True
Skeletal system provides ___________ to vital organs like the heart and the brain.
protection
Bones act as __________ for muscles.
levers
What is the primary function of bones in relation to muscles?
To provide attachment sites for muscles
What is the result of muscles being attached to bones?
Movement of joints
What is the role of tendons in the skeletal system?
To connect muscles to bones
What enables muscles to move joints in the body?
Attachment of muscles to bones
What is the relationship between muscles and bones in the skeletal system?
Muscles are attached to bones
What structure attaches bone to bone?
ligament
What attaches bone to muscle?
tendon
Where is blood cell formation done?
In the bone marrow of some bones.
Storage of minerals like Calcium and phosphorous
True
What is the bone cells?
Osteoblast, Osteoclast, Osteocyte
Allocate the correct corresponding bone information.
Osteoblasts = Cells that form the matrix of bone Osteocytes = These are osteoblasts that are trapped in the bony matrix called lacunae (like jail). Contact with other osteocytes and their blood supply is through cellular channels called canaliculi (like slots in a jail cell). Can revert back to osteoblasts if needed e.g. to form new bone after an injury. Osteoclasts = Cells that eat away at bone, Used to re-model bone that is not needed. Enable the body to extract Calcium from bones for use in blood, (“C” for “chewing” or “cleaning”) Cancellous Bone = Light, spongey
What is the two bone structures?
Cortical and Cancellous Bone
Bone structure allocations
Cancellous Bone = Light, spongey Cortical = Heavy, dense Compact Bone = Heavy, dense spongy bone = Light but very strong
Cancellous Bone Consists of a network of bony spicules called?
trabeculae
Bony spicules appear random but are organised into a mesh-like network along regions of biomechanical stress
True
Bony spicules appear random but are organised into a mesh-like network along regions of biomechanical stress
trabeculae
Can handle the forces from muscles, gravity and other bones
trabeculae
Spaces between the trabeculae contains _______
bone marrow
What is one of the functions of bone marrow?
Blood cell production and fat storage
What is the main purpose of bone marrow in the body?
To produce blood cells and store fat
What process occurs in bone marrow?
Haematopoiesis
What is haematopoiesis responsible for in the body?
Producing blood cells
What is an additional function of bone marrow besides haematopoiesis?
Fat storage
Allocate correct bone allocations
Cancellous Bone = Found in the end of long bones and surrounding the medullary cavity Cancellous Bone = Is surrounded by an outer layer of compact bone. bone marrow = Spaces in between the trabeculae contain trabeculae = Consists of a network of bony spicules called
Cancellous Bone overall function is?
strong but light-weight bone that allows for bone marrow storage and aligns to specific forces that the bone is under (trabeculae)
