General Knowledge
The name given to organisms that have a strong skeletal structure
What is vertebrates?
Also known as the collar bone
What is the clavicle?
It is any place where adjacent bones or bone and cartilage come together to form a connection
What is a joint?
The 3 kinds of muscles in the body.
The number of bones babies are born with.
What is 270?
Where both red and white blood cells are formed.
What is the tissue called bone marrow?
Also known as the shoulder blade
What is the scapula?
The 3 kinds of function of a joint.
What are immobile, slightly movable, and freely movable?
The types of fibers muscle tissues are made up of
What are protein fibers?
What 2 major minerals do bones mostly contain?
What are calcium and phosphorus?
Give 3 of 5 functions of the skeletal system
- Provide protection, support, movement, production of blood cells, storing minerals
Also known as the breastbone and the eye socket.
What is the sternum and the orbit?
Hinge and ball-and-socket are examples of this type of joint.
When the attachment is furthest away from the heart.
What is the insertion point of a muscle?
Explain the process of breathing in relation to movement and how it is a function of the skeletal system.
What is: the ribcage creates an up and down motion which changes the volume of the chest and results in air being drawn into or forced out of the lungs
The number of bones found in each hand and foot.
Hand - 27
Foot - 26
List the bones found in the leg, foot, and head area
Femur, tibia, fibula, patella, tarsal, metatarsal, phalanges, cranium, orbit, upper jaw, lower jaw (mandible)
The type of fluid found in the joints that act as a lubricant
What is synovial fluid?
When 2 muscles work in direct opposition to each other.
What are antagonistic pairs?
Give 3 examples of a long bone and the name of the outer and inner layer present.
What are: the femur, humerus, and clavicle. Outer layer - compact bone; inner layer - spongy bone
Bone - hard and rigid; protection, support and muscle attachment
Cartilage - cushioning layer at ends of bones; prevents bone rubbing
Tendon - tough and does not stretch; connects muscle to bone for contraction movement
Ligament - can stretch a little; connects bone to bone to allow movement at a joint
List the bones that are found in the arms, hands, and torso area.
Scapula, humerus, radius, ulna, carpals, metacarpals, phalanges, sternum, vertebral column, pelvic girdle, ribcage, clavicle
The two kinds of movement that a hinge joint can only permit.
What are flexion and extension?
The constant tension in the muscles against gravity at rest; how can its level increase?
What is muscle tone?
It can increase if you exercise regularly
What is tensile strength and elasticity of tendons and ligaments?
Tensile strength - withstand a lot of stretching and pulling
Elasticity - stretching of the ligaments so bones can move within a joint
