Unit 693: Veterinary Anatomy

1. Introduction to Veterinary Anatomy

• Anatomical terminology
  • Standard anatomical terms
  • Body planes: sagittal, transverse, dorsal
  • Directional terms: cranial, caudal, dorsal, ventral, medial, lateral
• Organization of the animal body
  • Levels of organization: cells, tissues, organs, systems
  • Overview of major body systems

2. Skeletal System in Veterinary Anatomy

• Functions of the skeletal system
  • Support, protection, movement, mineral storage, blood cell production
• Types of bones
  • Long, short, flat, irregular, sesamoid
• Bone structure
  • Compact vs. spongy bone
  • Bone marrow and growth plates
• Joints (Articulations)
  • Types: fibrous, cartilaginous, synovial
  • Joint movements and examples
• Skeletal variations across species

3. Muscular System in Veterinary Anatomy

• Muscle types
  • Skeletal, smooth, cardiac
• Muscle organization
  • Muscle fibers, fascicles, tendons, origin and insertion
• Muscle contraction mechanisms
  • Sliding filament theory (basic overview)
• Functions
  • Movement, posture maintenance, heat production
• Coordination with skeletal system

4. Digestive System in Veterinary Anatomy

• Overview of the digestive tract
• Oral cavity
  • Teeth types and functions
  • Salivary glands
• Esophagus
• Stomach
  • Types: monogastric vs. ruminant stomach anatomy
• Intestines
  • Small intestine: duodenum, jejunum, ileum
  • Large intestine: cecum, colon, rectum
• Accessory organs
  • Liver: functions and anatomy
  • Pancreas: exocrine and endocrine roles
• Digestion and absorption process

5. Respiratory System in Veterinary Anatomy

• Structure of the respiratory tract
  • Nose, nasal cavity, pharynx, larynx, trachea
  • Bronchi and bronchioles
  • Lungs and alveoli
• Mechanism of respiration
  • Inhalation and exhalation
  • Gas exchange process
• Species-specific respiratory adaptations

6. Circulatory System in Veterinary Anatomy

• Components
  • Heart anatomy: chambers, valves, conduction system
  • Blood vessels: arteries, veins, capillaries
• Blood composition and functions
• Circulation pathways
  • Systemic and pulmonary circulation
• Role in transport of oxygen, nutrients, and waste

7. Nervous System in Veterinary Anatomy

• Central nervous system (CNS)
  • Brain: major regions and functions
  • Spinal cord
• Peripheral nervous system (PNS)
  • Nerves and ganglia
• Functions
  • Sensory input, integration, motor output
• Reflexes and responses to stimuli

8. Reproductive System in Veterinary Anatomy

• Male reproductive anatomy
  • Testes, epididymis, vas deferens, accessory glands, penis
• Female reproductive anatomy
  • Ovaries, oviducts, uterus, cervix, vagina
• Gamete production and fertilization process
• Species-specific reproductive traits

9. Urinary System in Veterinary Anatomy

• Components
  • Kidneys: structure, nephron overview
  • Ureters, urinary bladder, urethra
• Functions
  • Filtration, urine formation, fluid and electrolyte balance
• Urine excretion process

10. Integumentary System in Veterinary Anatomy

• Skin structure
  • Epidermis, dermis, hypodermis
• Appendages
  • Hair, nails/claws, glands (sebaceous, sweat, scent)
• Functions
  • Protection, thermoregulation, sensory perception
• Species variations in integumentary systems
