Locate the delicate ureters that attach to the kidney and lead to the bladder. Wiggle the kidneys to help locate these tiny tubes. Procedure: Remove a single kidney (without damaging the other organs) and dissect it by cutting it longitudinally. Locate the cortex (the outer area) and the medulla (the inner area). Tap or move your mouse over the rat diagram below to view the organ names. *Tip: on smaller devices, you may want to flip your device to landscape if you can't see the full width of the image.

Rat Identification Rat Anatomy & Life Cycle
Rats are often used in dissection classes because they are readily available and they possess the typical mammalian body plan. Most of what you learn on the rat is applicable to the anatomy of other mammals, such as humans.. The diagram below illustrates the muscles of the ventral surface of the rat. Be able to identify those Dissection of Genital System. The rat is a typical mammal. Formerly guinea pig (Cavia sp.) (Fig. 19.1) were used for dissection in most of the undergraduate and postgraduate colleges in Indian Universities. Of late, due to prevailing high cost, guinea pig is being replaced by rat. Four species of rats are common in India, of which three are wild.

1. Locate the diaphragm, which is a thin layer of muscle that separates the thoracic cavity from the abdominal cavity. 2. The heart is centrally located in the thoracic cavity. The two dark colored chambers at the top are the atria (single: atrium), and the bottom chambers are the ventricles.

In this video, I talk you through how to do a dissection of a rat to highlight the major mammalian organ systems. It shows the excretory system, digestive sy.
[DIAGRAM] Female Rat Reproductive System Diagram
Conceptually, a neural circuit, network, or system may be viewed as a set of nodes or "parts"—including gray matter regions, neuron types, individual neurons, and synapses, considered at descending, nested levels of granularity—with a set of connections between nodes. This paper reports the availability of a high-resolution atlas of the adult rat. The atlas is composed of 9475 cryosectional images captured in 4600 × 2580 × 24-bit TIFF format, constructed using serial cryosection-milling techniques. Cryosection images were segmented, labelled and reconstructed into three-dimensional (3D) computerized models.
Availability: Rats are most frequently used as type specimen for mammalian dissection because they are readily available and they possess the typical mammalian body plan. Most of what you learn on the rat is applicable to the anatomy of other mammals, such as humans. Rats can be obtained from pet shops, biological supply companies or pharmaceutical firms. Female Reproductive System. The organs of the female reproductive system are specialized to produce ova (eggs), transport the egg cells to the site of fertilization, to provide a favorable environment for developing embryos, and to move offspring outside of the body (birth) at the appropriate time. The reproductive system also supplies.

Label the diagram using the descriptions and bold words. Trace the flow of blood using arrows. Branches of the Aorta The aorta has four general areas. Locate each of these on your rat. ascending aorta - the upper part of the vessel that starts at the atrium aortic arch - the place where the aorta bends to the left. The external anatomy encompasses the head (cranial region), neck (cervical region), chest (thoracic portion), pectoral (portion where forelegs attach), abdomen, pelvic (portion where hind legs attach), and tail. Though both sexes have teats, you can differentiate the male rat from the female rat.
