SEHS B.1.1. Anatomical Position, Planes and Movement

What is the primary function of the axial skeleton?

• Supports posture

• Stabilizes the appendicular skeleton

• Protection of vital organs

• Provides attachment site for muscles

Which bones are part of the appendicular skeleton?

• Sacral, Lumbar, Thoracic

• Skull, Ribs, Sternum

• Humerus, Femur, Tarsals

• Vertebral Column, Coccyx

What is the movement that decreases the angle between two body parts?

• Flexion

• Adduction

• Abduction

• Extension

Which plane separates the upper and lower halves of the body?

• Frontal Plane

• Sagittal Plane

• Transverse Plane

• Horizontal Plane

What is the axis of rotation that runs from front to back through the body's center of gravity?

• Transverse Axis

• Sagittal Axis

• Vertical Axis

• Frontal Axis

Which movement involves moving the limb in a circular motion, combining flexion, extension, adduction, and abduction?

• Inversion

• Circumduction

• Rotation

• Eversion

What is the function of the ribcage in the skeletal system?

• Protect vital organs - Surrounds the heart and lungs

• Support and posture - Provides a framework for the body

• Muscle attachment point - Bony landmarks provide attachment sites

• Store and release minerals - Stored and released for homeostasis

What bones make up the axial skeleton?

• Sacrum, Coccyx, Sternum

• Scapula, Clavicle, Patella

• Radius, Ulna, Phalanges

• Skull, Vertebrae, Ribs

What is the movement that turns the palm of the hand inward?

• Opposition

• Supination

• Pronation

• Reposition

Which plane separates the left and right sides of the body?

• Transverse Plane

• Sagittal Plane

• Horizontal Plane

• Frontal Plane
