The image displays the title 'INTRO TO SKELETAL SYSTEM' in large blue and black text, with a full human skeleton model standing centrally on a white background.
Handwritten notes define the axial and appendicular skeletons, stating the axial is the vertical axis and the appendicular is 'appended' to it, divided into girdles and limbs. It also notes a typical adult has around 206 bones.
An anatomical diagram shows anterior and posterior views of the human skeleton, labeling major bones like the skull, humerus, hip bones, and phalanges. A key differentiates axial (green) and appendicular (brown) skeleton components.
Handwritten notes list components of the Axial Skeleton (skull, ribs, vertebral column) and Appendicular Skeleton (pectoral girdle, upper limb, hip bone, lower limb), detailing specific bones within each category.
The image defines bone features: projections, depressions, cavities, and holes. A table provides examples of various bone features like processes, tubercles, spines, condyles, foramina, sinuses, and fossae.
A diagram illustrates the morphology of a long bone in longitudinal section, showing epiphysis, diaphysis, spongy bone, compact bone, marrow cavity, periosteum, endosteum, and articular cartilage.
The image presents an osteon diagram, detailing structures like the central canal, lacuna, collagen fibers, and concentric lamellae. Below it, a microscopic cross-section of an osteon at 400x magnification is shown.
A microscopic image of decalcified bone at 100x magnification shows the periosteum, cortical bone, osteon, endosteum, and marrow layers, illustrating the layered structure of bone tissue.
The image illustrates the three types of bone cells: osteoblasts (from osteogenic cells), osteocytes (depositing/reabsorbing matrix), and osteoclasts (removing collagen/minerals), showing their morphology and function.

A&P: Skeletal System

Hey girls! After a very long, long wait.. here are my quick notes for A&P the Skeletal System! This is an intro into it.

📝

In this section, I go over the axial and appendicular skeleton briefly. I mostly focus on bone morphology and structure in this section. I will make 2 more separate posts for Axial Skeleton and Appendicular Skeleton.

📝

I hope these notes help and if you have any questions, feel free to comment and I will gladly answer! Good luck!

... Read moreIn addition to my intro notes, it's helpful to understand how the axial and appendicular skeletons work together to support movement and stability in our body. The axial skeleton forms the central axis and includes the skull, vertebral column, ribs, and sternum, crucial for protecting vital organs like the brain and heart. The appendicular skeleton is made up of the limbs and girdles (pectoral and pelvic). It's designed for mobility and manipulation of the environment. Many students find it useful to study labeled diagrams when learning the appendicular skeleton since it includes many bones such as the humerus, radius, ulna in the upper limb, and femur, tibia, fibula in the lower limb. When reviewing bone morphology, focus on key terms like projections (processes, tubercles, trochanters), depressions (fossae, notches), and cavities (foramen, sinus). These features are important landmarks for muscle attachment and joint formation. Remember that bone structure includes cortical (compact) and cancellous (spongy) bone. Understanding microscopic features like osteons, lacunae, and the periosteum helps grasp how bones grow and repair. From my experience, sketching out simple labeled diagrams and identifying major bones on yourself or models really helps reinforce memorization and comprehension. Also, familiarizing yourself with terms like axial vs appendicular skeleton and their function improves your overall understanding and exam performance. Feel free to reach out if you want tips on tackling more detailed posts I’ll be sharing soon on axial and appendicular skeleton separately. Good luck with your studies!
