Study Notes
General Anatomy
- General Anatomy is the study of organism structure and parts.
- Anatomy is the scientific study of organism structure, including systems, organs, and tissues.
- Anatomy describes the shape, structure, and location of organs and systems.
- It also describes the relationship between organs.
Types of Anatomy
- Two main types of anatomy exist:
- Gross Anatomy: Examines organs through the naked eye. It includes superficial anatomy – the study of external body features.
- Microscopic Anatomy (Histology): Uses microscopes to view tissues and cells. It also includes histology (the study of tissues) and embryology (the study of an organism's immature stage).
Directional Terms
- Superior (Cranial): Closer to the head (e.g., the hand is superior to the foot).
- Inferior (Caudal): Closer to the feet (e.g., the foot is inferior to the hand).
- Anterior (Ventral): In front of (e.g., the breastbone is anterior to the spine).
- Posterior (Dorsal): Behind (e.g., the shoulder blades are posterior to the breastbone).
- Medial: Towards the midline of the body.
- Lateral: Away from the midline of the body.
- Proximal: Closer to the point of attachment of a limb to the body trunk.
- Distal: Farther from the point of attachment of a limb to the body trunk.
- Superficial: Closer to the body surface.
- Deep: Further from the body surface.
Anatomical Planes of the Body
- Coronal (Frontal): Divides the body into anterior and posterior portions.
- Sagittal: Divides the body into right and left portions.
- Median (Midsagittal): A specific sagittal plane passing through the midline of the body.
- Transverse (Axial): Divides the body into superior and inferior portions.
Anatomical Terms of Movement
- Flexion: Decreases the angle between two bones (bending).
- Extension: Increases the angle between two bones (straightening).
- Adduction: Movement towards the midline of the body.
- Abduction: Movement away from the midline of the body.
Body Cavities
- Body cavities are spaces that house internal organs (viscera).
- Two main cavities:
- Ventral Cavity: Front of the body, further subdivided into:
- Thoracic Cavity.
- Abdominal Cavity.
- Pelvic Cavity(part of the abdominopelvic cavity).
- Dorsal Cavity: Back of the body, further subdivided into:
- Cranial Cavity.
- Spinal Cavity.
- Ventral Cavity: Front of the body, further subdivided into:
