Study Notes
Introduction to Anatomy
- Anatomy is the scientific study of the structure of organisms and their parts.
- It includes the examination of macroscopic (visible to the naked eye) and microscopic (requiring a microscope) structures.
- Anatomy is closely related to physiology, which investigates the functions of these structures.
Levels of Organization in the Body
- Chemical level: Atoms and molecules combine to form complex structures.
- Cellular level: Cells, the fundamental units of life, are the building blocks of tissues.
- Tissue level: Similar cells grouped together to perform specific functions.
- Organ level: Two or more tissues working together for a particular function.
- Organ system level: Interconnected organs working for a common function.
- Organism level: The entire living being, encompassing all other levels.
Body Cavities
- Dorsal cavity: Protects the nervous system, subdivided into cranial (brain) and vertebral (spinal cord) cavities.
- Ventral cavity: Houses internal organs (viscera) and is further divided into thoracic (heart and lungs) and abdominopelvic (stomach, intestines, reproductive organs, and bladder) cavities.
- The diaphragm separates the thoracic and abdominopelvic cavities.
Anatomical Directional Terms
- These terms describe the position of body parts relative to each other.
- Superior/inferior: Above/below.
- Anterior/posterior: Toward the front/back.
- Medial/lateral: Toward the midline/away from the midline.
- Proximal/distal: Closer to the point of attachment/further from the point of attachment (limbs).
- Superficial/deep: On or near the surface/further from the surface.
- Ipsilateral/contralateral: Same/opposite side.
Body Planes
- Sagittal plane: Divides the body into left and right portions.
- Midsagittal plane: A vertical plane dividing the body into equal left and right halves.
- Parasagittal plane: A vertical plane dividing the body into unequal left and right halves.
- Frontal (coronal) plane: Divides the body into anterior (front) and posterior (back) portions.
- Transverse (horizontal) plane: Divides the body into superior (upper) and inferior (lower) portions.
- Oblique plane: Passes through the body at an angle.
Body Regions
- Head and neck.
- Thorax.
- Abdomen.
- Pelvis.
- Back.
- Upper limb (arm, forearm, hand).
- Lower limb (thigh, leg, foot).
Anatomical Imaging Techniques
- Radiography (X-rays): Uses ionizing radiation to create images of dense structures.
- Ultrasound: Generates images of soft tissues using high-frequency sound waves.
- Computed tomography (CT): Creates cross-sectional images using X-rays and computer processing.
- Magnetic resonance imaging (MRI): Generates detailed images of soft tissues using a magnetic field and radio waves.
- Positron emission tomography (PET): Measures metabolic activity in the body.
Basic Anatomical Terminology
- Common terms used to describe body structures and characteristics.
- Includes terms for organs, tissues, and structures.
Human Anatomical Reference Regions
- Precise anatomical definitions of body regions, used for study and reference.
- Specific definitions and examples for each region to provide clearer anatomical context.
