BIO 211L Midgley: Introduction to the Skeletal System 1. Introduction to the Axial and Appendicular Skeleton Reference - lab manual pg. 130, pg. 133 - 134 - Figure 8-3 and Figure 8-4 For each of the bones listed in the table below:  o pull out the corresponding bone from your bone box or skull box.  Take it over to an articulated skeleton and determine where it belongs in the body and how it is oriented o indicate whether it is from the axial or appendicular skeleton  o classify the bone according to its shape (long, short, flat, irregular, sesamoid)  Name Axial or Appendicular Shape Classification clavicle  tibia vertebra  humerus  carpal bones patella  temporal bone  sternum  metatarsal bones  sphenoid

BIO 211L Midgley: Introduction to the Skeletal System 2. Review the structure of a long bone Reference - lab manual pg. 137 - Figure 8-5 - review image on Blackboard > Mastering AP > Study Area > PAL > Human Cadaver > Appendicular Skeleton > Lower Limb > slide 10 Pull out a femur from your bone box i. Identify the components of a long bone - Diaphysis - Epiphysis - Epiphyseal line - Articular cartilage - Periosteum - Endosteum - Medullary cavity ii. Describe the location and function of yellow bone marrow iii. Describe the location and function of red bone marrow iv. What is the difference between an epiphyseal plate and an epiphyseal line? 3. Histology of Compact Bone

BIO 211L Midgley: Introduction to the Skeletal System Reference - lab manual pg. 150 - 157 - Blackboard > Mastering AP > Study Area > PAL > Human Cadaver > Axial Skeleton > Skull > images 1 – 10 - Complete Anatomy, a recommended course resource, can also be useful when navigating actual specimens / models in lab For now, we will focus on a small subset of bones and surface markings from the axial skeleton. Using your group's skull, work as a team to identify the bones, sutures, and foramina listed here: Cranial bones • frontal bone • parietal bones • temporal bones • occipital bone • sphenoid bone • ethmoid bone Cranial sutures • sagittal suture • coronal suture • squamous suture • lambdoid suture Facial bones • mandible • maxillae • lacrimal bones • zygomatic bone • nasal bones • vomer bone • inferior nasal conchae Cranial foramina • cribriform plates with olfactory foramina • optic canals • superior orbital fissure • foramen rotundum • forman ovale • foramen spinosum • foramen lacerum • internal acoustic meatus • jugular foramen • hypoglossal canals • foramen magnum
