Functional Anatomy Chapter 5
Animal Surfaces and Body Systems • Any discussion of the structure and function of animals begins with an understanding of the terms dorsal, ventral, cranial or anterior, and caudal or posterior.
Dorsal • Pertains to the upper surface of an animal.
Ventral • Relates to the lower or abdominal surface.
Anterior or Cranial • Applies to the front of head of an animal.
Posterior or Caudal • Pertains to the tail or rear of an animal.
Intro. • Physiology, or the life functions of horses, occurs in body systems. Nine body systems are found in animals, including horses.
Skeletal Muscular Digestive Urinary Respiratory Circulatory Nervous Reproductive Endocrine The Nine Systems
Axial Skeleton: skull, spine, ribs, and breastbone, pelvis, and tail Appendicular Skeleton: forelegs and hindlegs Skeletal System
Smooth Muscles: Ex. Digestive system and uterus of females Cardiac muscles: Found only in the heart. Striated orSkeletal Muscles: attach to bones Muscular System
