Pe Paper 1 Mock Flashcards
What are short bones and provide an example?
Short bones act as shock absorbers.
Example: Tarsals when landing a jump.
What is the primary function of long bones?
Long bones serve as levers for movement.
Example: The radius and ulna when throwing a shot put.
What connects bone to bone?
Ligaments connect bone to bone.
What connects bone to muscle?
Tendons connect bone to muscle.
List the functions of the skeletal system.
- Protection of vital organs
- Muscle attachment points for movement
- Production of blood cells
What type of bones protect vital organs?
Flat bones protect vital organs from damage.
How do muscles facilitate movement at joints?
Muscles attach to bones via tendons to allow movement at a joint.
What is produced in the bone marrow?
Blood cells are produced in the bone marrow.
What role do red blood cells (RBC) play in physical activity?
RBC carry oxygen to the working muscles.
What is the role of white blood cells (WBC) in the body?
WBC help prevent infections.
What minerals are stored in bones to make them strong?
Calcium and phosphorus.
What is the function of irregular bones?
Irregular bones provide protection and muscle attachment.
What is the primary function of flat bones?
Flat bones are primarily for protection of vital organs.
What type of joint allows for flexion and extension?
Hinge joints (e.g., knee and elbow).
What type of joint is the shoulder?
Ball and socket joint.
Fill in the blank: The ________ connects the knee cap to the leg.
Patella
What joint type is found in the neck?
Pivot joint (atlas and axis).
What are the movements allowed by a condyloid joint?
Flexion and extension.
What muscle attachment allows a basketball player to jump?
The gastrocnemius attaches to the foot for plantar flexion.
True or False: The femur is an example of a short bone.
False.
What is an antagonistic muscle pair?
Two muscles that work together to cause movement; when one muscle contracts, the other relaxes.
What is the agonist in muscle movement?
The muscle contracting which causes the movement.
What is the antagonist in muscle movement?
The muscle relaxing during movement.
What is the agonist and antagonist for flexion at the elbow?
Agonist = bicep, Antagonist = triceps.
