EXERCISE Introduction to the Skeletal System and the Axial Skeleton LEARNING OUTCOMES These Learning Outcomes correspond by number to the laboratory activities in this exercise. When you complete the activities, you should be able toc Activity 7.1 Activity 7.2 Lo LABORATORY SUPPLIES Anatomical model of compact and spongy bone Humerus or femur, longitudinal . Classify bones according to their shapes. Differentiate between the axial skeleton and appendicular skeleton. Describe the microscopic structure of compact and spongy bone. Describe the arrangement of compact and spongy bone in the bones of the skeleton. Understand the functions of bone markings on bones. Identify the bones of the skull and their bone markings from various views Compare the bones of the fetatskull and the adult skull Recognize the general featuresof the vertebral column. Cranial bones, cross section Human skeletons Disarticulated bones of the human skeleton . . Activity 7.3 - Human skulls - Brain models . Fetal skuills Activity 7.4 Activity 7.5 Activities 7.6-7.9 Vertebrae from cervical (including C, and Cal thoracic, and lumbar regions . Sacrum and coccy Ribs . Colored pendils Activity 7.10 Activity 7.11 Activities 7.12-7.13 Compare the unique features of d weirtebrse from different regions of the vertebral coigtne Describe the structure of the Activity 7.14 thoracic cage PRE-LAB QUIZ Before you begin, read all the activities in Exercise 7 and the required reading in your textbook that is assigned by your instructor 1. During this laboratory exercise, you will classity bones according toand 2. Consider the following supply list: a skeleton, a heart model a skull individual vertebrae a brain model and a model of bone tissue. To complete all the activities in this laboratory exercise, which item on the list will not be used? 3. True or False: Osteons are the basic functlional units of spongy bone 4. True or False: The carpal bones are classified as short bones S. What type of bone has a shaft (dilaphysis) and two expanded knoblike ends (epiphyses)? units of spongy bone 6. The skullis composed of two distinct groups of bones: the cranial bones and the bones 7. The- vertebrae articulate (formjoints) with the ribs. 8. In the fetal skull the developing cranial bones are connected by areas of fibrous connective tissue called 9. True or False: In a typical vertebra, the pedicles and larminae form the spinous process 10. True of False: The costal cartilages of vertebrosternal ribs are directly atached to the sternum. 83Explanation / Answer
introduction to skelatal system - skelatal system means the frame work of the body bones and connective tissue to support the tissue,muscles and to protect the interal organs ofhe body there are around 206 types of bones in the body of human.the main function of the skelatal system is protection,support,movement,calcium and mineral storage in the body.
there are basicaly five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.
There are three main types of joints in human body ; Fibrous (immovable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint.
1. during the laboratory experiment the bones are classified according to there Shapes.
2.the brain model and heart model are not used in the skelatal system experiment.
3.False -The functional unit of compact bone is an osteon,
4.True-The carpals are classified as short bones.
5. Femur - type of bone has a shaft and two expanded knoblike ends.
6.The skull consists of two sets of bones: the cranial and the facial bones.
7.12 thoracic vertebrae articulate with the ribs.
8.The skull bones are connected by fibrous joints called sutures.
9.true -the typical vertebra the pedicle form spinous process
10. true -directly to the sternum by costal cartilages .
