Study Notes
Chapter 1 - Orientation of the Human Body
-
Anatomy: The study of the structure of the human body.
- Gross anatomy: Studying structures visible to the naked eye, such as through dissections.
- Microscopic anatomy: Studying structures that require a microscope, like histology (tissues).
- Surface anatomy: Studying structures that can be seen on the body's surface.
-
Hierarchy of structural organization:
- Chemical level: Atoms combine to form molecules. ~90% of the human body is composed of four elements: Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N).
- Cellular level: Cells and their functional subunits. Humans have 50-100 trillion cells. Millions of cells die and are created every minute.
- Tissue level: Groups of cells working together with a similar function. Examples include epithelial, connective, muscle, and nervous tissues.
- Organ level: Multiple tissues come together to form organs. Specific qualifications need to be met to be considered an organ; include a defined structure, a variety of tissues, and connective tissue. Examples include bones, blood vessels, etc.
- Organ system level: Multiple organs working together to perform a particular function.
- Organismal level: The whole, functioning human body.
Anatomical Position
- Anatomical Position: Standing upright, facing forward, eyes forward, palms facing forward with thumbs pointed away from the body.
Directional Terms
- Superior/Cranial: Towards the head.
- Inferior/Caudal: Away from the head.
- Anterior/Ventral: Towards the front of the body (for four-legged animals, not synonymous with ventral)
- Posterior/Dorsal: Towards the back of the body.
- Medial: Towards the midline of the body.
- Lateral: Away from the midline of the body.
- Proximal: Closer to the point of attachment to the body (used for limbs).
- Distal: Farther from the point of attachment to the body (used for limbs).
- Superficial: Closer to the body surface.
- Deep: Farther from the body surface.
- Ipsilateral: On the same side of the body.
- Contralateral: On the opposite side of the body.
Body Planes and Sections
- Coronal/Frontal plane: Divides the body into anterior (front) and posterior (back) portions.
- Sagittal plane: Divides the body into left and right portions.
- Median/Midsagittal plane: Sagittal cut precisely along the midline of the body.
- Transverse plane: Divides the body into superior (upper) and inferior (lower) portions (also called a cross-section).
- Oblique plane: Divides the body at an oblique angle.
Body Cavities
- Body Cavities: Internal spaces within the body that house and protect organs.
- Dorsal body cavity: Posterior part of the body
- Cranial cavity: Contains the brain.
- Vertebral cavity: Contains the spinal cord.
- Thoracic cavity: Contains the heart and lungs.
- Superior mediastinum: Upper mediastinum
- Pleural cavities: Contain the lungs
- Pericardial cavity: Contains the heart.
- Ventral body cavity: Anterior part of the body.
- Abdominal cavity: Contains digestive organs.
- Pelvic cavity: Contains reproductive organs and urinary bladder.
- Abdominopelvic cavity: The abdominal and the pelvic cavity are often considered as one complete cavity. This is because the cavities are interconnected.
- Dorsal body cavity: Posterior part of the body
Regional Anatomy
- Regions are labeled in the provided text and divided into axial and appendicular. It mentions specific body region names such as cephalic, thoracic, abdominal, vertebral, etc.
Body Cavities Membranes
- The internal cavities are lined with membranes that can help protect the internal organs.
- Mucous membranes: Line passages that communicate with the outside environment (e.g., digestive, respiratory tracts).
- Serous membranes: (serous membrane lining)
- Cover internal organs and cavities not open to the outside (e.g., heart and lungs) which are often found in pairs where one portion covers the tissues and the other covers the cavity
