After completing this laboratory you should be able to:   1)   Describe the developmental of the coelom in vertebrates;   2)   Describe how each of the subdivisiona of the body cavities forms and what the relationship of each is to the viscera;   3)   Identify each of the specific digestive structures listed below and briefly describe its physiological function;   4)   Identify each of the specific respiratory structures listed below and briefly describe its physiological function.     I.  BODY CAVITIES   1)   Work through Z&K exercise #7, involving opening the body cavities of the shark, mudpuppy and cat.  Pay special attention to the relationships between body cavities and the defining membranes.   2)   Review your text to be sure that you understand the basic developmental pattern of body cavities, especially the embryological origin of the coelom and how parietal and visceral layers, mesentaries, suspsensory membranes, and omenta form.   II.  DIGESTIVE SYSTEM   1)   Work through Z&K exercise #7, involving exposing and identifying external and internal structure of digestive organs.   2)   Be able to identify structures on the organ list below for this lab.   3)   Be able to relate gross and microscopic anatomy of each organ to function.  Be able to desribe anatomical and functional organ specializations for the shark, mudpuppy and cat.   Structures to identify:          Shark:         Oral Cavity             teeth         Pharynx             gill slits             gill rakers             gill pouches             gills             spiracles         Alimentary Tract             esophagus             stomach                   rugae                   pyloric sphincter             duodenum             spiral intestine                   spiral valve             rectum             cloaca         Glands             ventral pancreas             dorsal pancreas             liver             gall bladder             Cat:         Oral Cavity             vestibule             teeth             tongue                 taste buds             hard palate             soft palate         Pharynx             oropharynx                   glottis                   epiglottis             laryngeopharynx         Alimentary Tract             esophagus             stomach                   cardia                   fundus                   pyloris                   rugae                   pyloric sphincter                   greater and lesser curvatures             small intestine                   duodenum                   jejunum                   ileum                   ileocecal valve             colon                   cecum                   ascending colon                   descending colon             rectum             anus             Glands             parotid salivary gland             submandibular salivary gland             sublingual salivary gland             ventral pancreas             dorsal pancreas             liver                   right medial and lateral lobes                   caudate lobe                   left medial and lateral lobes             gall bladder             hepatic, cystic, common bile ducts       Necturus:         Oral Cavity             teeth             internal nares             tongue         Pharynx             gill slits             glottis         Alimentary Tract             esophagus             stomach             duodenum             small intestine             large intestine             cloaca         Glands             pancreas             liver             gall bladder         III.  PRESPIRATORY SYSTEM   1)   Work through Z&K exercise #8, involving the respiratory systems of the shark, mudpuppy and cat.   2)   Be able to identify structures on the organ list below for this lab.   Structures to identify:          Shark:       Pharynx             gill slits             gill rakers             gill pouches             gills             spiracles             Cat:         Nasal Cavity         Pharynx             nasopharynx                   internal nares             oropharynx         Larynx             hyoid bone             epiglottis             thyroid cartilage             cricoid cartilage             false vocal cords (venticular folds)                   glottis             true vocal cords (vocal folds)         Trachea             cartilage rings             trachealis muscle         Primary Bronchi         Lungs             lobes         Diaphragm             central tendon             esophageal hiatus             crus muscles             phrenic nerves         Necturus:         external gills         lungs
