Axial Skeleton Lab 1 
BCS 145 LAB: AXIAL SKELETON
WHY ARE WE DOING THIS LAB? The skeletal framework of the body is composed of at least 206 bones and the associated tendons, ligaments, and cartilages. The skeletal system has a variety of important functions, including, the support of soft tissues, blood cell production, mineral/electrolyte and lipid storage, and, through its relationships with the muscular system, the support and movement of the body as a whole. Skeletal system disorders can thus affect many other systems. The skeletal system is in turn influenced by the activities of other systems. For example, weakness or paralysis of skeletal muscles will lead to a weakening of the associated bones and may cause changes in their relative positions.
Procedures:
Part A – Familiarization with Bone Terminology
Go to station “A” and find the letter with corresponds to the structures and surface features recorded in Part A of your answer sheet.
Part B – Categorizing Bones
Go to station “B” and find the bones labeled 1-8. Name the bone, and then categorize the bone as short, long, flat, or irregular. Record your answers in Part B of your answer sheet.
Part C – Demonstrate your Knowledge
Write the name of the bone, marking, surface feature, or structure from the axial skeleton next to the description.
Part D – Learn the Bones, Structures, and Surface Markings
With the remainder of the lab, your job is to learn the names of the axial bones, specific structures of the bones, and the names of specific surface markings. The pages in the text which outline the axial skeleton are pages 212-235. Below is the list of bones, structures, and surface markings you will be held responsible for knowing. (Bold print terms are the major bone and the terms in italics are important markings or structures of that particular bone)
Frontal bone
Parietal bone
Temporal bone Mandibular fossa, external acoustic meatus, styloid process, mastoid process, carotid canal, jugular foramen
Occipital bone
