Format: PDF / Kindle (mobi) / ePub
Offering comprehensive coverage of core anatomic concepts, this respected, clinically oriented text is the definitive source for a complete understanding of veterinary anatomy. Gain the working anatomic knowledge that is crucial to your understanding of the veterinary basic sciences, as well as detailed information directly applicable to the care of specific animal species, including dogs, cats, horses, cows, pigs, sheep, goats, and birds. Each chapter includes a conceptual overview that describes the structure and function of an anatomic region, accompanied by new full-color dissection photographs that illustrate the relevance of anatomy to successful veterinary practice.
Content is logically organized into two main sections - a general introduction to mammalian anatomy and a region-specific breakdown - to make studying more efficient and ensure greater understanding.
Comprehensive, all-in-one coverage of all major species presents everything you need to master anatomic concepts in one text.
Focus on essential anatomy of each species delivers just the right level of detail to help you establish a solid foundation for success.
For the first time all images in the text appear in full color! This lifelike presentation clarifies anatomic concepts and structures in vibrant detail.
Vivid full-color dissection photographs help you translate anatomic knowledge to clinical practice and confidently perform dissection procedures.
A companion Evolve Resources website reinforces your understanding and helps you prepare for the NAVLEÒ board exam with 300 exam-style practice questions, a full-color electronic image collection, and more.

THE DEVELOPMENT OF THE UROGENITAL APPARATUS DEVELOPMENT OF THE URINARY ORGANS The intermediate mesoderm reflects in muted fashion the segmentation that is so evident in the adjoining somites. It soon forms in its caudal domain a continuous solid longitudinal (nephrogenic) thickening from which arise, in craniocaudal and temporal sequence, three attempts at the formation of an excretory organ. The first attempt constitutes the pronephros, which forms in the
In the next stage of development the mesoderm is locally transformed to create a series of cartilaginous models in the pattern of the adult bones. These precursors soon come to resemble the final forms in broad outline; they remain ensheathed by thin coverings of the unmodified mesoderm, now appropriately known as perichondrium. Dense mesoderm also remains between the cartilages where the joints will develop. The cartilage models grow mainly by interstitial growth, in which each part expands more
internal organs by their size, configuration, and consistency. Nonetheless, variation is great and is affected by many factors that make it difficult to know whether one should expect to be able to identify certain organs in all normal subjects, which is, itself, another useful lesson. Palpation through the skin can be supplemented by digital or manual exploration per rectum and per vaginam. Certain organs may be identified by percussion to elicit resonance when the overlying skin is struck a
enigmatic because its proximal attachment suggests that it is a potential flexor of the stifle; stifle and hock, however, normally move in unison. The apparent contradiction in these actions is not easily explained. It has been suggested that the prime function of the muscle is not to move either joint but to oppose bending of the tibia, ensuring that the strain is always directed along its long axis. The superficial digital flexor (Figure 2–65/8) arises from a supracondylar fossa or tubercle on
these species the parotid gland extends rostrally onto the masseter muscle, ventrally toward the angle of the jaw, and caudally toward the atlantal fossa. In all species it is enclosed within a fascial covering that sends trabeculae inward to divide the gland into obvious lobules. The major collecting ducts run within these trabeculae and eventually join to form a single duct that leaves the cranial aspect. In the dog this duct takes the shortcut across the lateral surface of the masseter to open
