Chapter 14 Flashcards
How many bones does your skeletal system consist of?
206
What are the many functions your skeletal system has?
- Providing support for the body
- Protecting internal tissues and organs from injuries
- Acting as a framework for attached muscles
- allowing movement of limbs and digits
- producing new red and white blood cells
- storing fat and minerals, such as calcium and phosphorus
What are the three types of connective tissue?
Cartilage, ligaments, and tendons
Cartilage
a strong, flexible connective tissue that can act as a cushion between two bones to reduce friction
Ossification
the process by which bone is formed, renewed and repaired
Ligament
a band of fibrous slightly connective tissue that attaches one bone to another
Tendon
a fibrous cord that attaches muscle to the bone
Joints
points at which bones meet
What are the three types of fractures
- Hairline Fracture: if parts of the bone do not separate
- Transverse Fracture: when the fracture is completely acr5oss the bone
- Comminuted Fracture: when the bone shatters into more than two pieces
What are typical joint injuries?
- Dislocation: when a bone slips out of place
- Torn cartilage: from a sharp blow to a joint
- Bursitis: from the inflammation of bursa
- Bunioins: swellings of the bursae
- Arthritis: inflammation of joints
Carpal tunnel syndrome
when ligaments and tenons in the wrist swell
At what age do your bones stop growing?
Approximately 25 years old
What do your muscles do even while your asleep?
Muscles help you breathe, your heart beat, and digest food
What are the three types of muscles?
Smooth muscle, skeletal muscle, and cardiac muscle
Smooth Muscles
muscles that act on the lining of the body’s passageways and hollow internal organs
Skeletal Muscles
muscles attached to bone that cause body movements
Flexor
the muscle that closes a joint
Extensor
the muscle that opens a joint
Cardiac muscle
type of striated muscle that forms the wall of the heart
What are five tips that can help you care for your muscular system and maintain muscle tone?
- Get regular exercise
- Eat high-protein foods to build muscle
- Practice good posture to strengthen back muscles
- Use proper equipment and clothing during physical activities
- Warm up correctly and stretch before exercising and cool down
