- Uses Latin and Greek terminology
- Learning anatomical terminology is essential for progressing in anatomy
- Anatomical language is a fundamental medical terminology
- Terminologia Anatomica (TA) is the international standard for anatomy terminology
Anatomical Position
- Standard reference position of the body
- Used to describe the location of structures

Cavities of the Body
- Most anatomical structures are found within cavities, which are fluid-filled areas
- Membranes and other structures divide these bodily cavities, providing protection, lubrication, and reducing friction during organ movement
- Each cavity contains unique neurovascular structures and organs specific to its location
- Examples of cavities:
- Ventral or anterior cavity (including the thorax, abdomen, and pelvis)
- Dorsal or posterior cavity (including the cranial and spinal cavities)
- Thoracic cavity
- Abdominopelvic cavity
- Cranial cavity
- Vertebral cavity
Osteology
- Characteristics of bone:
- Living tissue
- Supports the body's skeleton
- Complex, rigid, inflexible, hard, vascular, and dynamic connective tissue
- Composed of cells and intercellular matrix substances
- Types of bone cells:
- Osteoblasts
- Osteocytes
- Osteoclasts
- Bone growth occurs through surface accretions, also known as appositional growth
- Bone function:
- Providing the skeletal frame and body architecture
- Preventing the collapse of the body
- Protecting internal organs from impact-related injuries
- Facilitating the movement of body parts
- Supporting blood formation and the generation of red and white blood cells
- Participating in the buildup and release of substances and minerals
Bone Ossification
- There are two varieties of bone ossification:
- Intramembranous ossification
- Endochondral or intracartilaginous ossification
- Intramembranous ossification:
- Directly replaces the membrane with bone without intervening cartilage stages
- Found in the skull vault and several facial bones
- Endochondral ossification:
- Occurs in the long and short bones of the skeleton
- A model of the bone is first laid down in hyaline cartilage derived from connective tissues in the embryo
Skeletal System
- Divided into two groups:
- Axial skeleton (80 bones)
- Appendicular skeleton (126 bones)
- Axial skeleton:
- Cranium (29 bones)
- Vertebral column and thorax (51 bones)
- Appendicular skeleton:
- Upper extremity bones (64 bones)
- Lower extremity bones (62 bones)
Bones' Types and Classification
- There are two types of bone:
- Compact bone
- Spongy (trabecular or cancellous) bone
- Classification of bones based on anatomical shape:
- Long bones
- Short bones
- Flat bones
- Irregular bones
- Sesamoid bones### Scapulae
- Triangular bone located at the 2nd to 7th levels of the ribs
- Connects the clavicle to the humerus
- Has two faces: costal (anterior) and posterior surfaces
- Features three borders: superior, medial, and lateral borders
- Has three angles: superior, inferior, and lateral angles
Posterior Surface of Scapula
- Convex and features a protrusion called the spine of scapula
- Spine of scapula divides into two concave surfaces: supraspinous fossa and infraspinous fossa
- Supraspinous fossa filled by the supraspinatus muscle and infraspinous fossa filled by the infraspinatus muscle
- Deltoid and trapezius muscles attach to the spine of the scapula
Borders of Scapula
- Superior border: shortest and thinnest, with a slight concave shape
- Lateral border: strong and thick, situated closest to the axilla
- Medial border: long, medial edge of the scapula closest to the vertebral column
Angles of Scapula
- Superior angle: formed by the junction of the superior and medial borders
- Inferior angle: formed by the junction of the medial and lateral borders
- Lateral angle: formed by the junction of the superior and lateral borders, contains the head and neck of the scapula
Glenoid Cavity
- Shallow pit on the lateral margin of the scapula's head, forms the glenohumeral joint with the head of the humerus
- Above the glenoid cavity: a small ridge called the supraglenoid tubercle, where the long head of the biceps brachii muscle attaches
- Below the glenoid cavity: a roughened area known as the infraglenoid tubercle, where the long head of the triceps brachii muscle attaches
Acromion and Coracoid Process
- Acromion: broad, straight lateral extension of the spine of scapula, articulates with the clavicle at the acromioclavicular joint
- Coracoid process: thick, beak-like structure that projects anterolaterally from the lateral end of the scapula
Humerus
- Longest bone in the upper limb, located in the arm (brachium)
- Divided into three main regions: proximal extremity, body, and distal extremity
Proximal Extremity of Humerus
- Consists of several structures, including the head, anatomical neck, greater and lesser tubercles, surgical neck, and the upper half of the body
- Head of humerus: rounded and articulates with the glenoid cavity
- Lesser tubercle: small, jagged ridge below the head, situated at the anterior proximal end of the humerus, and medial to the greater tubercle
Body of Humerus
- Also known as the body of the humerus, is the middle portion of the bone
- Features deltoid tuberosity, a rough area on the lateral side of the body where the deltoid attaches
Distal Extremity of Humerus
- Known as the condyle, located on the lateral side of the distal end of the humerus
- Spherical capitulum: articulates with the head of the radius
- Trochlea: roller-shaped, articulates with the ulna
- Medial and lateral epicondyles: knob-like prominences on the distal, medial and lateral sides of the humerus
Clinical Correlation
- Fractures of the humerus: can lead to direct injury or compression of the axillary nerve, radial nerve, and median and ulnar nerves
- Medial epicondyle fracture: can result in ulnar nerve injuries
- Lateral epicondyle fracture: can result in radial nerve injuries
Radius
- Bone located on the lateral side of the forearm (antebrachium)
- Responsible for pronation and supination movements
- Articulates with the humerus, radius, scaphoid, and lunate bones
- Upper end of the radius: the proximal extremity, is the thickest and strongest part
- Head of the radius: articulates proximally with both the humeral capitulum and the radial notch of the ulna at the elbow joint
Ulna
- Bone located on the medial side of the forearm (antebrachium)
- Articulates with the radius and humerus
- Does not have direct contact with the wrist bones; instead, there is a disc between them
- Upper end of the ulna: the proximal extremity, is the thickest and strongest part
- Olecranon: elbow protrusion, forms the uppermost part of the ulna, and can be easily palpated
Bones of the Hand
- The hand skeleton consists of 27 bones and can be divided into three groups: carpal bones (8), metacarpals (5), and phalanges (14)
- Carpal bones: eight small bones that form the wrist
- Metacarpals: five bones in each hand, each with a head, body, and base from proximal to distal
- Phalanges: 14 bones in each hand, with two in the thumb and three in the other fingers
