SPLANCHNOLOGY Rudy Soekamto Setiabudi Edited by Hana eliyani
SPLANCHNOLOGY • Science which study viscera of animals. • The root” sphlancnon” means internal organ (the entrails). • Viscera includes only the organs belonging to the systems that maintain the life of the individual and secure the continuity of the species, example: • digestive, respiratory andurogenital System.
Structure in general • Structure organs with or without a cavity, always surrounded by and, if hollow lined by special layers. Whether hollow or solid, most viscera are prominent in the cavity of the body. • Viscera lined by layers : serous (outer wall) muscular (middle wall) mucous (inner layer).
SPLANCHNOLOGY • Apparatus digestive deals with food. • Apparatus respiratory with gases. • Apparatus urinary removes the residues, as do the other two systems also to maintain the metabolic balance and, consequently, that of life itself. • Apparatus genitalia for perpetuate the species.
BODY CAVITY • Mamalia have two cavities: thorax cavity and abdominal cavity separated by diaphragm. • thorax & abdominal organs were protected by membrane (pleura, pericardia and peritoneum,) this layers produces mucous liquid in the cavity for protecting the adhesion and friction.
system digestive = apparatus digestorius =systema digestorium • Composes of organs which receive & digest the food. • This tube run along the body, starts from lips until anus • example : mouth, pharynx, esophagus gaster, intestine & accessory organs: teeth, tongue, salivary glands, liver and pancreas.
Canalis alimentarius Tractus digestivus (canalis alimentarius) composes of : • esophagus, • Ventriculus • intestinum tenuae & • intestinum crassum
oralcavity • LABIUM • LINGUA • DENTES • PALATUM MOLLE • PHARYNX • GLD. SALIVA
Oral Cavity cavum oris tongue Gld sublingualis
tongue (LINGUAE) • Position in the mouth between rami mandible • Fix in radix linguae • Dorsal surface is free = dorsum lingua. • On the mucousa surface have papillae, filiformes, fungiformes, vallatae, foliatae & conicae. • Salivary glands sublingualis/buccalis. • Support by intrinsic &extrinsic muscles • Arteri/vena/nervus
Function of the tongue • is very motile, it shows differences in structure according to its varying usage for the species. • Function: • Intake of solid & liquid food (licking and sucking). • Grasp and sort of food • Taste the food. • Mastication & deglutitation. • Cleansing of the skin and hair coat.
LINGUA HORSE p.vallate tonsil p.foliate
lingua radix epiglottis oesophagus • Facies dorsal have: • papillae filiformis • papillae fungiformis • papillae circumvalatae • papillae foliatae Corpus lingua apex lingua
SALIVARY Glands • The ducts open into the mouth. • 1. parotid gland (under the ear). 2. mandibular gland (under the lower jow). 3. sublingual gland (under the tongue)
salivary glands cattle gld.parotis gld mandibula
Salivary glands cattle gld parotis gld buccalis dorsales gld mandibularis Gld buccales ventrales
TEETH ( DENTES) • portion within a socket in the upper and lower jaw and a portion exposed term as crown (corona). • In the interior of the teeth is a pulp cavity containing soft material and including vessels & nerves. • Function :d.Incisi biting, d.canini tearing, d.premolar and molar chewing food. • Deciduous teeth (baby teeth) will replace with permanent • Composition of teeth such as. pulp (gelatin, blood vessels & nerves), dentin, enamel and cementum.
DENTES • animal I C PM M • horse 2X (3/3 1/1 3-4/3 3/3) = 40/42 • bovine 2X (0/4 0/0 3/3 3/3) = 32 • pig 2X (3/3 1/1 4/4 3/3) = 44 • dog 2X (3/3 1/1 4/4 2/3) = 42 • cat 2X (3/3 1/1 3/2 1/1) = 30
TEETH (dentes) dentin enamel cementum Pulp cavity

TEETH DOG Carnissial teeth
PHARYNX & palatum molle • In the crossing of digestive system with respiratory system.
PHARYNX • Have 7 opening: * ostium pharyngeum tubae auditivae ( 2 ) * isthmus faucium * choanae ( 2 ) * aditus oesophageum * aditus laryngea
ESOPHAGUS • Musculomembranous tube which extends from the pharynx to the stomach, start from cervical till abdomen • Length in HORSE: 125 to 150 cm. • Its in median plane, its course from dorsal larynx and trachea. level VC IV turn to the left trachea, in VC VI parallel and continue ventral trachea, then enters thorax cavity until VT III, the position turn to dorsal trachea, continue caudally parallel and in the left aorta, both of them inthe mediastinum continue between two lung piercing diaphragm ( hiatus esophageal and aorticus), and finally end in the cardia of the ventriculus, at the level costae XIV
Position of esophagus • horse bovine trachea oesophagus
Ø esophagus horse, VC II esophagus trachea
Ø eso vertebrae C IV ( caudal view) • Esophagus at the sinister trachea.
ABDOMINAL CAVITY • The biggest cavity. Separate from thorax cavity by diaphragm. Continue caudally as pelvis cavity. • Dorsal border : muscles and vert.lumbal • Lateral border: muscles and fascia abdominal & m iliacus, cartilago costae asternale & diaphragm. • Ventral border: muscles and abdominal aponeurosa & cartilago xyphoid. • Cranial border : diaphragm,
peritoneum • is the thin serous membrane which lines the abdominal cavity & pelvis cavity (PERITONEUM PARIETALIS), and covers to a greater or lesser extent, the viscera contained therein. PERITONEUM VISCERALIS) except kidney (ren). • In the male covers properly the genital. • In the female have 2 holes for tuba Fallopii & uterus, • In several location, make fold such as fold for holding term: mesenteries, omentum, ligaments, etc
VENTRICULUS = GASTER • Is the large dilatation of GIT. Intervenes between esophagus and small intestine. • Digest by mechanic and enzymatic. • Structure has variation depend on their food : Simple stomach: equidae & carnivora Complex stomach : ruminansia Chane stomach : pig has deverticulum ventriculi.
Ventriculus horse • horse : look like J ; Volume 8 – 15 liter • cattle Volume : 115-150 • Hanging by; ligamentum & omentum.
Ventriculus HORSE Saccus cecus ventriculi Margo plicatus Pars cardiaca curvatura minor oesophagus pylorus Pars fundica curvatura major Incisura angularis
VENTRICULUS ruminansia reticulum omasum rumen curvatura dorsal reticulum abomasum curvatura ventral sinister dexter
CALF (baby cattle) • rumen + reticulum have not function, make the milk directly go to the abomasum via sulcus ventriculi. • 8 mgg: volume rumen + reticulum = abomasum. • 12 weeks: r+r = 2 times abomasum
mucous ventriculus • Rumen : the most part thickly sudded with large papillae like “towel” pilae ruminis • Reticulum: raise into folds like bees house cellulae reticularis • Omasum : have about hundred longitudinal folds lamina omasi. • Abomasum : the surface is soft and has a reddish color and is marked by large permanent folds Plicae abomasi

TRACTUS RESPIRATORIUS Respiration organ function in the Organism for : • Breath (respiration); as osmotic and chemical process, the gasses exchange with their environment. • The gas exchange between oxygen (O2) and Carbondioksida (CO2) (drawn in/ inspiration and expelled/ expiration). Its happen in the lung organ by the oxidative activity (diffusion) in the tissue.
TRACTUS RESPIRATORIUS • Start from: nose (planum nasale), nose cavity (Cavum nasi), pharynx, larynx, trachea, bronchi until lung (bronchioli and sacculi alveolares). Supporting organs: >Pleura >Skeleton thoracalis (sternum, costae, V.Thoracalis + respiratory muscles) >Diaphragm.
