Anatomy-Skeletal System Axial Skeleton

Anatomy-Skeletal System Bell Work 1 person from your table grab 1 mini skeleton 1 person from your table grab supply boxes Grab wkst from front table On your bell work sheet, list as many bones as you can remember that we covered yesterday on the skull {11} (independent work!)

Using the tape at your tables, grab the sharpie and label the tape 1-11 Mastoid process 7. Nasal Parietal 8. Sphenoid Temporal 9. Occipital Frontal 10. Mandible Orbit 11. Maxilla Zygoma

Anatomy-Skeletal System Objectives Students will be able to: Define anatomical terms. Identify the bones of the axial skeleton. Label the bones.

Anatomy-Skeletal System Terminology Axial Skeleton Consist of bones that form the axis of the skeleton; the skull, spinal column, breast bone and ribs. Support and protect the organs of the head, neck and thorax.

Anatomy-Skeletal System Terminology Articulate/Articulation To unite by forming a joint/joints Facet A small, smooth, flat surface on a bone

Anatomy-Skeletal System Terminology Foramen A natural opening, especially through a bone Process A projection away from the main part of the bone

Anatomy-Skeletal System Axial Skeleton Vertebra Spinous process Transverse process Vertebral foramen Vertebral body Facet

Anatomy-Skeletal System Axial Skeleton Intervertebral Disk The intervertebral disks are situated between the vertebral bodies of each vertebra

Anatomy-Skeletal System Axial Skeleton Vertebra Comparison As the vertebral column moves from the cervical region to the lumbar region, the spinous process becomes shorter and angled more inferiorly. Spinous process changes lead to a decrease in mobility The vertebral body becomes larger Vertebral body changes are necessary to bear more weight Body Spinous Process

Closure In your own words… Define foramen Define process List the bones of the axial skeleton What is lateral curvature of the spine called? What part of the vertebra must get bigger as we progress down the spine?

DO NOT TOUCH THE BONES AT YOUR TABLES! Bell Work On your bell work sheet, define the terms foramen, articulation, and process What bones make up the axial skeleton? What is their main purpose? DO NOT TOUCH THE BONES AT YOUR TABLES!
