Study Notes

Course Objectives

Anatomy refers to the structure of living organisms, divided into:
- Histology (microscopic anatomy)
- Gross anatomy (non-microscopic anatomy)
Physiology encompasses the functions of living organisms, including:
- Chemical and physical processes essential for life
- Multiple levels of approach

Body Organization

Molecular level
Organelle level
Cellular level
Tissue level
Organ level
Organ system level (includes integumentary, skeletal, muscular, endocrine, nervous, circulatory, digestive, reproductive)
Organism level

Importance of Body Organization

Relevant in clinical practice
Fulfills natural curiosity about life processes

Anatomical Nomenclature

Reference planes:
- Sagittal: Vertical plane, divides body laterally
- Coronal (Frontal): Vertical plane, divides ventral and dorsal
- Transverse: Horizontal plane, divides superior and inferior

Human Brain Sections

Recognizes three main planes: transverse, coronal, sagittal

Major Body Positions

Superior (cranial)
Inferior (caudal)
Anterior (ventral)
Posterior (dorsal)
Internal (deep)
External (superficial)
Proximal
Distal
Medial
Lateral

Major Body Regions

Cephalic: Includes cranial and facial regions
Cervical: Neck area
Trunk: Divided into:
- Thorax
- Abdomen
- Pelvis
Upper appendages
Lower appendages

Body Cavities

Dorsal cavity consists of:
- Cranial cavity
- Vertebral cavity
Ventral cavity consists of:
- Thoracic cavity:
  - Pleural cavities
  - Pericardial cavity
- Abdominopelvic cavity (peritoneal):
  - Abdominal cavity
  - Pelvic cavity

Body Membranes

Characterized by thin layers of epithelial and connective tissue
Functions to cover, separate, and support internal organs
Types of membranes include:
- Serous membranes: Secrete aqueous or salt solutions; line body cavities.
  - Classes:
    - Pleura: Lines thorax, includes visceral and parietal pleura
    - Pericardium: Surrounds the heart, includes visceral and parietal pericardium
    - Peritoneum: Lines abdomen, includes visceral and parietal parts
    - Mesenteries: Double folds of peritoneum connecting visceral and parietal layers
- Mucous membranes: Secrete mucosaccharide solutions; line cavities open to exterior (oral & nasal cavities, respiratory, digestive, reproductive, and urinary tubes)
