Study Notes
Anatomical Position and Directions
- Anatomical position refers to the body standing upright, with feet shoulder-width apart, toes forward, and palms facing forward.
- Anterior (ventral) describes the front or direction toward the front of the body.
- Posterior (dorsal) describes the back or direction toward the back of the body.
- Lateral describes the side or direction toward the side of the body.
- Medial describes the middle or direction toward the middle of the body.
- Superior (cranial) describes a position above or higher than another part of the body.
- Inferior (caudal) describes a position below or lower than another part of the body.
Body Cavity and Membranes
- Coelomic cavities are body cavities that do not open to the outside.
- Cerebrospinal fluid (CSF) is a colorless fluid produced by the brain that cushions the brain and spinal cord within the posterior cavity.
- Pleura is the membrane that wraps around the outside of the lungs and lines the inside of the chest cavity.
- Pericardium is the membrane that separates the heart from other mediastinal structures.
- Parietal layer is the outermost layer of the pleura.
- Visceral layer is the innermost layer of the pleura that is superficial to the lungs.
- Mucous membrane lines the body cavities and hollow passageways that open to the external environment.
- Synovial membrane is a thin layer that lines the inner surface of the joint cavity at a synovial joint and produces synovial fluid.
Tissue and Orientation
- Connective tissue is a type of tissue that serves to hold in place, connect, and integrate the body's organs and systems.
- Epithelial membrane is epithelium attached to a layer of connective tissue.
- Cutaneous membrane is epithelial tissue made up of stratified squamous epithelial cells that cover the outside of the body (skin).
- Deep describes a position farther from the surface of the body.
- Superficial describes a position nearer to the surface of the body.
- Prone describes a face-down orientation.
- Supine describes a face-up orientation.
Planes and Body Regions
- Frontal plane is a two-dimensional, vertical plane that divides the body or organ into anterior and posterior portions.
- Sagittal plane is a two-dimensional, vertical plane that divides the body or organ into right and left sides.
- Distal describes a position in a limb that is farther from the point of attachment or the trunk of the body.
- Proximal describes a position in a limb that is nearer to the point of attachment or the trunk of the body.
