Chaper 4: Structures and Functions of Musculoskeletal System Flashcards
(28 cards)
The muscular and skeletal systems are usually referred to jointly as the?
Musculoskeletal System.
Why are the muscular and skeletal systems usually referred to jointly as the Musculoskeletal System?
Because they work together to provide form, support, stability and movement of the body.
What does muscles make possible?
Movement.
What generates nearly 85% of the heat that keeps the body warm?
Movement.
What moves food through the digestive tract?
Mucles.
What aids the flow of blood through the veins and move fluids through the duct and tubes of other systems?
Muscles.
What does the Skeletal System consist of?
Bones, cartilage, joints, synovial fluid, ligaments, tendons, and bursae.
The Bone acts as?
The framework of the body, support and protects the internal organs.
What does Bone stores?
Calcium, mineral required for normal nerve and muscle function.
What is Cartilage?
Smooth, elastic connective tissue, acts as a shock absorber between bones.
Cartilage makes up the flexible parts of the body such as?
The outer ear and the tip of the nose.
What is a Joint?
The point where two or more bones meet together surrounded by ligaments, tendons and muscles that hold the joint together.
What does Synovial Membranes line?
The outermost layer of a joint and secrete synovial fluid.
Why the Synovial Fluid acts as a lubricant?
To reduce friction and make the smooth movement of the joint possible.
What is a Ligament?
A band of fibrous tissue that connects bones or joins a bone to cartilage.
What is a Tendon?
A narrow band of dense, fibrous connective tissue that attaches a muscles to a bone.
What is a Bursa?
A fibrous sac, acting as a cushion to aid movement in areas where a tendon passes over a bone like shoulder, elbow and knee joints.
The composed of bony Vertebrae, the Vertebral Column is also known as?
The bacbone.
What does the Vertebral Column supports?
The head and keeps the trunk erect.
What does the Vertebral Column houses and protects?
The spinal cord.
What is the Spinal Cord?
A tube-like bundle of nerves that carries messages from the brain to the rest of the body.
Separated by discs made of cartilage, Why Vertebrae functions as cushions?
To reduce the force on the spine generated by movements like walking, running and jumping.
What form the Vertebral Column?
The Vertebrae and discs extend the length of the spine.
The Vertebrae Cervical refers to?
Neck.
