Study Notes
Introduction to Anatomy and Physiology - Unit 1
- Session Outcomes: Students will be able to:
- Describe basic anatomical terms.
- Use these terms to describe normal movement.
Anatomy and Physiology
-
Anatomy: The study of structures that make up the body and how they relate. Derived from the Greek word "Anatome," meaning "to cut up."
-
Subspecialties of Anatomy:
- Gross anatomy: Study of body structures without a microscope.
- Microscopic anatomy (Histology): Study of tissues using a microscope.
- Developmental anatomy: Study of anatomical changes across the lifespan.
- Embryology: Study of development of structures before birth.
- Systemic anatomy: Study of functional relationships of organs within a system.
- Regional anatomy: Study of body parts regionally.
-
Physiology: The study of how the body and its parts work or function. Derived from the Greek word for "study of nature."
Level of Structural Organization of the Body
- Homeostasis: The body's ability to maintain a stable internal environment despite external changes. Adaptive mechanisms (like hormones) maintain normal parameters.
- Structural Levels:
- Atoms
- Molecules
- Compounds
- Cells
- Tissues
- Organs
- Organ Systems
- Organism
Cells, Tissues, and Organs
- Cell: The smallest independent unit of life, crucial for growth, metabolism, irritability, and reproduction.
- Tissues: Various similar cells working together, divided into four types: epithelial, connective, nervous, and muscle.
- Organ: Two or more types of tissues working together to perform a specific function. (e.g., the stomach).
- Systems: Groups of organs that work together for major body functions (e.g., respiratory system).
Anatomical Terminologies
-
Anatomical Position: Universally accepted standard: standing erect, facing forward, feet together, palms facing forward.
-
Relative Directional Terms:
- Used to describe the location of body parts relative to one another. Examples: superior/inferior, anterior/posterior, medial/lateral, proximal/distal, superficial/deep.
-
Body Parts Regions:
- Axial: Head, neck, thorax, abdomen, pelvis
- Appendicular: Upper and lower extremities.
- Abdominal Subdivisions: Nine regions or four quadrants used to describe more specific areas within the abdomen.
Body Cavities
- Body Cavities: Spaces within the body housing internal organs (viscera).
- Ventral cavity: Larger, front-facing cavity further divided into the thoracic (lungs, heart) and abdominopelvic cavities.
- Dorsal cavity: Smaller, back-facing cavity (cranial: brain, vertebral: spinal cord). -Specific abdominal and pelvic regions.
Planes & Sections
- Body Planes: Imaginary surfaces splitting the body into sections for better understanding and identification.
- Sagittal (left-right halves), mid-sagittal (equal halves), parasagittal (unequal halves)
- Frontal or coronal (front-back halves)
- Transverse or horizontal (upper-lower halves)
- Oblique (other angle)
- Anatomical Axes: The axis around which planes are rotated
- Movement Terms: Flexion (forward movement), Extension (backward movement), Abduction (away), Adduction (towards), Rotation (around an axis).
Bone, Joints, and Muscles
-
Bones: The structural framework for support, protection, movement, and leverage.
-
Types of Bones:
- Long (e.g., femur)
- Flat (e.g., skull)
- Short (e.g., carpals)
- Irregular (e.g., vertebrae)
- Sesamoid (e.g., kneecap)
-
Joints: Areas where bones connect, allowing various degrees of movement.
- Types of Joints: Synovial (freely moveable), fibrous, cartilaginous.
-
Ligaments: Strong connective tissue connecting bones to provide stability.
-
Muscles: Provide movement by contracting.
- Skeletal Muscles: Connect to bones to effect movement via tendons.
