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
- Thoracic 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
- Classes:
- Mucous membranes: Secrete mucosaccharide solutions; line cavities open to exterior (oral & nasal cavities, respiratory, digestive, reproductive, and urinary tubes)
-
Serous membranes: Secrete aqueous or salt solutions; line body cavities.
Announcements
