Exploring Human Anatomy and Physiology

What are the main components of the human skeletal system?

• Bones, cartilage, ligaments, tendons, axial skeleton, appendicular skeleton

• Muscles, nerves, skin

• Hair, nails, teeth

• Blood, plasma, lymph

How many bones are in the adult human body?

• 206

• 198

• 210

• 204

What is the primary function of the axial skeleton?

• To produce red blood cells in the bone marrow.

• To provide support and protection for the body's central axis.

• To store fat and minerals in the body.

• To facilitate movement of the limbs.

Name the types of joints found in the human body.

• rotating, flexible, immovable joints

• Hinge, ball-and-socket, pivot, saddle, gliding, condyloid joints.

• circular, linear, composite joints

• fixed, sliding, elastic joints

What role do ligaments play in the skeletal system?

• Ligaments connect muscles to bones and facilitate movement.

• Ligaments connect bones to other bones and provide stability to joints.

• Ligaments are responsible for producing blood cells in the bones.

• Ligaments serve as the primary source of energy for the skeletal system.

Describe the process of muscle contraction.

• Muscle contraction happens when actin filaments push myosin heads away.

• Muscle contraction is initiated by the release of adrenaline into the bloodstream.

• Muscle contraction is the process where myosin heads pull actin filaments, shortening the muscle fiber.

• Muscle contraction occurs when calcium ions bind to myosin heads.

What are the three types of muscle tissue?

• Skeletal, Cardiac, Smooth

• Voluntary, Involuntary, Striated

• Tendons, Ligaments, Cartilage

• Epithelial, Connective, Nervous

How do skeletal muscles differ from smooth muscles?

• Both skeletal and smooth muscles are striated and involuntary.

• Skeletal muscles are striated and voluntary, while smooth muscles are non-striated and involuntary.

• Skeletal muscles are involuntary and smooth muscles are striated and voluntary.

• Skeletal muscles are non-striated and voluntary, while smooth muscles are striated and involuntary.

What is the function of the nervous system?

• To circulate blood and oxygen throughout the body.

• To provide structural support and shape to the body.

• To digest food and absorb nutrients.

• The function of the nervous system is to transmit signals and coordinate bodily functions.

Identify the main components of the central nervous system.

• Brain and spinal cord

• Heart and lungs

• Kidneys and liver

• Stomach and intestines
