Warm Up!How many bones make up the adult skeleton?Where are the tiniest bones in the skeleton located?What is the largest bone in the body?
Bones of the Skull:There are 8 immovable bones called cranial bones. They form the casing that surrounds the brain.
The three tiny bones located in the middle ear that
transmit sound vibrations are the Anvil, Hammer, and
Stirrup.
Facial Bones:
14 of them form the face
13 of the bones are interlocking and immovable and the 14th bone is the mandible.
Spinal Column
- consists of 24 separate
bones called vertebrae.
The first two vertebrae that forms your neck in the Cervical region on which your head pivots on are called:
Joints:- allow for movement to occurThe ends of some bones are covered with:- thin membranes- cushioned with layers or pads of cartilage
Joint Capsule:
It is lined with a membrane, and the membrane secretes a fluid called
Synovial Fluid.
Class Activity:You and your partner will complete the worksheet – “Joint Classifications, Types, and locations.”
Rules for Activity
- Work quietly!
- Stay on task.
- Complete the worksheet.
- Although you are working together, each one must write their own answers.
3 Basic Classifications:
1. Freely Moveable Joints
2. Partially Immovable Joints
3. Immovable Joints
Facts:The more freedom of movement within a joint the less stability it has. - Reduced or limited movement means increased stability and support.
