Week 2 quiz #1: True or False?

False: Gliding joints allow sliding movements.

A gliding joint allows rotation of one bone relative to another.

False: Abduction is away from the midline. Adduction is toward the midline.

Abduction occurs in the frontal plane as a movement toward the midline of the body.

False: Synarthroses are the least movable joints, whereas diarthroses are freely movable.

Freely movable joints are functionally classified as synarthroses.

True

In anatomical terms, anterior means "toward the front of the body" and posterior means "toward the back of the body".

True

In anatomical terms, lateral refers to something located toward the sides of the body, and medial refers to something located toward the midline of the body.

True

Joints that allow a small amount of movement are functionally classified as amphiarthroses.

False: Ligaments attach bone to bone. Tendons attach muscle to bone.

Ligaments are fibrous tissue that connect muscle to bone.

True

Plantar flexion is a movement specific to the ankle in which the toe moves posteriorly away from the anterior lower leg (shin) in the sagittal plane.

True

Retraction is a movement of the scapulae toward the midline of the body.

True

Rotation is a pivoting motion that occurs within the transverse plane about the longitudinal axis of the body or body segment.

True

Shoulder flexion is an anterior action of the shoulder joint which occurs in the sagittal plane about a frontal axis of rotation.

True

The axial skeleton forms the major axis of the body and consists of the skull, hyoid bone, rib cage, sternum and vertebral column.

True

The diaphysis is the shaft of bone made of hard compact bone with a central medullary canal filled with yellow bone marrow.

True

The frontal plane is a plane that passes through the body from side to side, dividing the body into anterior and posterior portions.

True

The functions of the skeletal system are support, movement, protection, mineral storage, and blood cell production.

False: The coxal bones articulate anteriorly at the pubic symphysis and posteriorly with the sacrum.

The pelvic girdle is composed of a pair of innominate or coxal bones which articulate anteriorly with the sacrum and posteriorly at the pubic symphysis.

False

The sagittal plane corresponds with the longitudinal axis of rotation.

True

The shoulder girdle (pectoral girdle) consists of the clavicles and the scapulae and is classified as part of the appendicular skeleton.

False: The tibia is located in the lower leg medial to the fibula.

The tibia is a bone of the lower leg which is located lateral to the fibula.

True

True of false? The transverse plane is a plane that passes horizontally through the body and divides the body into superior and inferior parts.
