Study Notes
Orientation to the Human Body (Part III)
- The study of anatomy and physiology uses specific terms for clarity.
- Scientists and healthcare professionals use a common language of special terms when referring to body structures and their functions.
- The language of anatomy, precisely defined, ensures clear communication.
- Special terminology prevents misunderstandings.
Learning Objectives
- Define anatomy and physiology.
- Describe the various branches of anatomy and physiology.
- Describe the different levels of structural organization in the human body.
- List and describe the body systems.
- Understand the basic life processes.
- Explain the homeostasis process.
- Understand the feedback control of homeostasis.
- Understand basic anatomical terminologies.
- Describe anatomical positions, names, and planes.
- Describe body cavities and their contents.
- Describe abdominal regions and their contents.
The Language of Anatomy
- Scientists and health professionals use a common language to describe body structures and functions.
- Anatomical terms have precise definitions.
- This language prevents misunderstandings.
- Precise terms are used to describe body positions, directions, regions, and structures.
Body Positions
- The anatomical position is a standard position for describing body parts and regions.
- In anatomical position the individual is upright facing forward with arms at the sides and palms facing forward.
- Descriptions of body parts assume the standard anatomical position.
- Body positions for reclining are termed supine (lying faceup) or prone (lying facedown).
Regional Terms
- Regional terms describe specific areas of the body.
- These terms are used to precisely locate structures.
- Regional terms are used in body descriptions and directional terms for precise location of body parts.
Directional Terms
- Directional terms describe the relative positions of body parts.
- The terms are used in comparisons and explanations of body regions and organs.
- Superior refers to a position above another.
- Inferior is a position below another.
- Anterior means in front of.
- Posterior is behind.
- Medial is on the midline.
- Lateral is on the outside of the midline.
- Intermediate is between 2 structures.
- Ipsilateral is on the same side as another structure.
- Contralateral is on the opposite side from another structure.
- Proximal is nearer to the point of origin or attachment.
- Distal is farther from the point of origin or attachment.
- Superficial is closer to the surface.
- Deep is farther from the surface.
Body Planes and Sections
- Body sections are cuts along imaginary planes.
- Body planes are used for viewing structures.
- Frontal (coronal) plane divides anterior and posterior parts.
- Sagittal plane divides left and right.
- Median or midsagittal plane divides the body into equal right and left halves
- Transverse (horizontal) plane divides superior and inferior parts.
- Oblique planes cut at any angle.
Body Cavities
- Body cavities enclose internal organs.
- Cranial cavity—contains the brain.
- Vertebral canal—contains the spinal cord.
- Thoracic cavity—contains the heart and lungs.
- Pleural cavities—contain the lungs
- Pericardial cavity—contains the heart.
- Mediastinum—contains the heart, thymus, and large vessels.
- Abdominopelvic cavity—contains the abdominal and pelvic cavities
- Abdominal cavity—contains stomach, spleen, liver, gallbladder and part of the intestines.
- Pelvic cavity—contains urinary bladder, reproductive organs, and parts of the intestines.
- Other body cavities such as oral (mouth), nasal (nose), orbital (eyes), and middle ear cavities.
Thoracic and Abdominal Cavity Membranes
- Serous membranes line cavities and cover organs.
- The membranes consist of parietal layers, which line the cavities, and visceral layers, which cover organs.
- Pleural membranes line the lungs and chest wall.
- Pericardial membranes line the heart.
- Peritoneum membranes line the abdomen.
- The membranes contain serous fluid reducing friction, this allows organs to move easily.
Serous Membranes
- Serous membranes are thin, double-layered membranes that surround organs in the body cavities.
- The visceral layer of a serous membrane is located directly on the organ.
- The parietal layer of a serous membrane lines the body cavity.
Abdominopelvic Regions and Quadrants
- The abdominopelvic cavity is divided into 9 regions or 4 quadrants to help locate organs.
Other Body Cavities
- The oral cavity contains the tongue and teeth,
- The nasal cavity is in the nose.
- The orbital cavities contain the eye.
- The middle ear cavities house small bones.
- The synovial cavities are located in joints, and contain synovial fluid.
