Introduction to Bones

Introduction to Bones

  • Overview of the skeletal system, its functions, and the components involved in the study of bones.

Colored Pencils

  • Tools needed for the lab session along with potential instructions and resources available.

Lab Instructions

  • Reference to the use of 'A&P Revealed' E-text for anatomical and physiological studies.

Labeling Diagrams

  • Importance of accurately labeling diagrams in understanding the skeletal system.

The Process

  • Methodology for correctly labeling the bones based on images and diagrams.

Learning Terms

  • Key vocabulary and terminology related to anatomy and bone structure.

Using A&P Revealed for Practice

  • Utilization of 'A&P Revealed' for practice and reinforcement of anatomical knowledge.

Skeletal System Function

  • Structure/Support for human body.

  • Facilitates Movement: Bones serve as attachment points for muscles, aiding in locomotion.

  • Protection of Internal Organs: Ribs form a protective cage around vital organs like the heart and lungs.

  • Production of Blood Cells: Bone marrow plays a crucial role in hematopoiesis, the production of blood cells.

  • Mineral and Fat Storage: Bones act as reservoirs for minerals (like calcium) and fats.

Bones of Skeletal System

  • Divided into Two Groups:

    • Axial Skeleton: Consists of bones along the body’s midline (skull, vertebrae, ribs).

    • Appendicular Skeleton: Includes the bones of the limbs and pelvic girdle (arms and legs).

Activities

  • Practice Labeling the Bones of the Articulated Skeleton: Engaging in exercises to label an articulated skeleton.

  • Use A&P Revealed: Utilizing the e-text resources for additional practice.

Bone Classification

  • Bone: Two categories - Axial or Appendicular.

  • Color Coding and Identification: Color code each bone representation for clarity.

  • Common Names of Bones: e.g., Malleus, Incus, Stapes (Ear bones), Carpals, Clavicle, etc.

List of Bones

  • Ear Bones: Malleus, Incus, Stapes

  • Miscellaneous Bones: Carpals, Clavicle, Coccyx, Femur, Fibula, Humerus, Hyoid, Metacarpals, Metatarsals, Os Coxae, Patella, Phalanges, Radius, Ribs, Sacrum, Scapula, Skull, Sternum, Tibia, Ulna, Vertebral Column.

Learning Bones in the Disarticulated Skeleton

  • Instructions on matching disarticulated bones to their labeled pictures in provided materials.

  • Name, Number, and Identification of Bones: Structure a table to identify bones on the left and whether they are right or left.

Disarticulated Skeleton Activity

  • Practical identification tasks involving various bones:

    • Femur

    • Position: Posterior (Left), Anterior (Right)

    • Scapula

    • Position: Anterior (Right), Posterior (Right)

    • Os Coxae

    • Position: Medial (Right), Anterior

Bone Markings

  • Definitions and observations of various bone markings vital for anatomical terminology.

General Observations

  • Projections or Elevations: Descriptions of major projections including:

    • Process: A projection or bump typically for muscle attachment.

    • Ramus: An extension of bone that creates an angle with the remainder of the structure.

    • Trochanter: A large, rough projection for muscle attachment.

    • Tuberosity: A small, round projection.

Specific Terms for Bone Projections

  • Crest: A prominent ridge.

  • Tubercle: Small, rounded projection (small tuberosity).

  • Line: A low ridge.

  • Spine: A pointed process.

Process Formations

  • Detailed definitions and types of processes:

    • Head: Expanded articular end of an epiphysis, separated from the shaft by a neck.

    • Neck: Narrow connection between the epiphysis and diaphysis.

    • Condyle: Smooth, rounded articular process (bump).

    • Epicondyle: Process near a condyle (a bump on a bump).

    • Trochlea: Smooth, grooved articular process shaped like a pulley.

    • Facet: A small, flat articular surface.

    • Fossa: Shallow depression that receives an articulating bone.

    • Notch: V-like depression in the margin of a flat area.

    • Sulcus: A narrow groove.

    • Foramen: Rounded passageway (hole) for blood vessels or nerves.

    • Canal: Passageway through bone.

    • Fissure: Elongate cleft, crack-like opening for blood and nerves.

    • Meatus: Tube-like opening or channel.

Openings in Bone Anatomy

  • Foramen: Corresponds to rounded passageways for blood vessels or nerves. Consider the following structures:

    • Canals, Fissures, Meatuses and Sinuses for their respective functions.

Bone Features Summary

  • Recap of key characteristics and features associated with different bones and their markings based on their functions and anatomical relevance.

Activities for Bone Marking/Definitions

  • Engaging in identification and matching bone markers to their definitions and identifying common features on specific bones.
