KINE 2850 Structural Kinesiology - Bones, Joints and Muscles of the Trunk and Spine

A collection of flashcards summarizing key concepts from the lecture on structural kinesiology related to the bones, joints, and muscles of the trunk and spine.

What are the major components of the trunk in the axial skeleton?

The trunk contains the skull, spinal column, ribs, sacrum, and sternum.

What is the main functional component of the trunk?

The spine is the major functional component of the trunk.

What are the movements of the spine in the frontal plane?

Lateral flexion and rotation.

What is the primary movement restriction in the thoracic region?

Trunk flexion is limited by the ribs.

How many cervical vertebrae are there in the spine?

There are 7 cervical vertebrae in the spine.

What are the two unique vertebrae in the cervical spine?

The Atlas (C1) and the Axis (C2).

What is the shape of the cervical and lumbar curves of the spine?

Both are concave posteriorly (lordotic).

What does a herniated disc result from?

Weakening and/or compression of the annulus fibrosus leading to nucleus pulposus protrusion.

What is the primary role of normal spinal curves?

They strengthen the spine and help absorb shock.

What are the three types of ribs based on their attachment to the sternum?

True ribs (1-7), false ribs (8-10), and floating ribs (11-12).
