Study Notes
Introduction to Human Anatomy
- Anatomy is the identification and description of the structural makeup of living things.
- It's a branch of biology and basic medicine.
- Anatomy has six main branches:
- Gross Anatomy: systemic or region-wise study, encompassing cadaveric anatomy and osteology (bone study).
- Histology (Microscopic Anatomy): study of tissues.
- Cytology and Cytogenetics (Cell Biology): study of cells.
- Embryology (Developmental Anatomy): study of embryo development from fertilization to fetal stage.
- Surface Anatomy: study of anatomical landmarks visible on the body's surface.
- Radiological Anatomy: study of anatomy using imaging techniques.
Anatomy Subdivisions
- Gross anatomy is further subdivided into:
- Surface anatomy (external body)
- Regional anatomy (specific regions of body)
- Systemic anatomy (specific organ systems)
- Microscopic anatomy is further subdivided into cytology (cells) and histology (tissues).
Relationship of Anatomy to Other Fields
- Anatomy is closely related to physiology (study of function), biochemistry, comparative anatomy, and embryology.
- Knowledge of anatomy is crucial for understanding human biology and medicine.
Dissection
- Dissection is the process of disassembling an organism to understand internal structure and the relationships between components.
- Anatomy describes structure and location, providing a framework for understanding how components interact to create a functioning whole.
Regional Anatomy
- Regional anatomy is commonly used in modern teaching because it's easier to apply to clinical settings compared to systemic anatomy.
Terminologies
- Learning anatomy is like building a house; strong foundations last longer.
- Anatomical terminology is important for consistent communication.
- The anatomical position is a universal reference point for describing body structures.
- All anatomical terms relate structures and their relationships.
- The person is considered standing upright with arms hanging at the sides and palms facing forward, thumbs pointing out. Feet are parallel to each other and toes are pointed forward.
Directional Terms
-
Using directional terms like anterior, posterior, superior, and inferior, anatomists can describe the relative position of parts of the body compared to each other.
-
Anatomists use terms like superior or cephalic, inferior or caudal, anterior or ventral; posterior or dorsal for locating parts of the body compared to each other.
-
Anatomists use terms like medial, lateral, proximal and distal to compare anatomical locations of parts.
-
Medial means closer to the midline. Lateral means further from the midline.
-
Proximal means closer to the origin or point of attachment. Distal means further from the origin or point of attachment.
-
Cranial and caudal describe locations in reference to the nose. Cranial is closer; caudal is further from the nose.
-
Superficial and deep identify position relative to the surface of the body. Superficial is closer to the surface; deep is further from the surface.
-
Anatomical terms relate location and positions to each other within the body. Using the referenced "standard" or anatomical positions minimizes confusion.
Body Planes and Axes
- Coronal (frontal), sagittal, and transverse (axial) planes are used to view body structures from specific perspectives.
Body Movements
- Depending on the type of joint, there are various movement capabilities possible.
- Common movements include flexion, extension, abduction, adduction, rotation, circumduction, supination, pronation, and repositioning.
- Examples: flexion (e.g., bending arm at elbow), extension (e.g., straightening leg), abduction (e.g., moving arm away from midline).
- Other movements involve the movements of head, neck, limbs, feet, and hands.
- Examples: Rotation (e.g., moving head from side to side), circumduction (e.g., moving arm in a circle).
Anatomical Regions
- The human body is divided into regions for easier organization, such as the head, neck, thorax, abdomen, upper and lower extremities.
Surface Anatomy
- Surface anatomy describes observable anatomical landmarks on the body's surface.
- Various markings and features of the body are highlighted.
Body Cavities
- Body cavities are spaces within the body that contain vital organs.
- There are cranial, thoracic, abdominal, pelvic, and vertebral cavities.
- Thoracic cavity is further subdivided into pleural, pericardial, and mediastinal cavities.
Anatomy vs Physiology
- Structure and function are related.
- The smallest functional unit is the cell, contributing to compartmentalization.
- Cells become tissues, then tissues become organs, and organs form systems.
Functional State
- Anastomoses are connections between previously branched structures, like blood vessels.
- A patent structure is abnormally open, such as a patent ductus arteriosus.
- A plexus is a net-like arrangement, such as nerves.
Classification of Joints
- Joints are connections between bones.
- Joints are classified by tissue types (fibrous, cartilaginous, synovial)
- Joints are classified by their degree of movement permitted (synarthrosis, amphiarthrosis, diarthrosis).
