Study Notes

Skeletal System Functions

The skeletal system provides support, protection, and movement for the body.

Types of Bones

Short bones are approximately as broad as they are long.
Irregular bones have shapes that do not fit into the categories of long, short, or flat bones.

Long Bone Anatomy

The diaphysis is the shaft of long bones.
The epiphyses are located at the ends of the bone and may likely be surrounded by articular cartilage if it articulates with another bone.

Bone Structures

Foramina are openings in bones that allow for the passage of nerves and blood vessels.
The vertebral foramen is a triangular opening in the vertebrae.

Axial Skeleton

The axial skeleton consists of 80 bones.
The cervical vertebrae have a wider transverse body and a triangular vertebral foramen.

Sternum

The xiphoid process is the sword-shaped lower part of the sternum, composed of three parts.

Upper Limb

The scapula is the bone that forms the shoulder girdle and has a coracoid process for muscle attachments.
The forearm consists of two long bones.
The carpal bones are a group of eight short bones in the wrist.

Vertebral Column

The lumbar region has a normal curvature known as lumbar lordosis.
The cervical vertebrae are characterized by small bodies, bifid spinous processes, and transverse foramina.

Scapula

The glenoid cavity is a structure located in the superior lateral portion of the scapula and articulates with the head of the humerus.
The coracoid process is attached to some shoulder and arm muscles via the scapula.
