The lower jaw of frog is moveable and it can up and down in vertical plane. It connects the cavity of the pharynx and middle ear to open into internal ear. These occupy the maximum portion of upper jaws and form a socket for eyes.į) Eustachian tube: there are two small spindle shaped opening one on either side situated laterally near the jaw angles called Eustachian tube. The middle one is larger is called median sub rostral fossa while other two are smaller and is called lateral sub rostral fossae.ĭ) Internal nares: internal nares are two in no.lying closed outside the patches of vomarine teeth.Į) Bulging of eyeballs: there are two large and oval area on the roof of upper jaws and called the bulging of eye ball. They are simply serving to preserve the captured smooth prey from the slipping out.Ĭ) Fossae: there are three pits are situated at tip of upper jaw just near the premaxillary teeth called fossae. The teeth of frogs not help in cutting, grinding and mastication of food. The inner side of teeth is hollow and is called pulp nourishing the tooth during the growth. The crown is covered with hard and shining white substance called enamel. It is composed of hard substance called dentine. It is formed of a bone like material, whereas the upper part is called the crown. The wide lower part of teeth is called root or base. The tooth is conical in its shape and consists of two regions: a base and crown. Structure of teeth: the teeth of frog acrodont, homodont and polyphyodont. They are called the vomarine teeth as they are born in vomer. It helps in closing the tip of mouth.ī) Vomarine teeth: these are the two small patches of teeth bending backwards and are found one or either side of the median line of the roof of the buccal cavity. At the tip of the mouth, the maxillary teeth are more pointed called the premaxillary teeth. These teeth breaks occasionally and is replace by new ones.this is known as polyphyodont condition. All teeth are of the same size and are called homodont type. Such type of teeth is known as acrodont teeth. These are directly attached with the maxilla. These are sharply pointed and not fixed in the sockets. The following structure found on the upper jaws:Ī) Maxillary teeth: maxillary teeth are the situated on the either side of upper jaw. This process is known as ingestion.īuccal cavity: Mouth leads into the buccal cavity and it is a wide space between upper and lower halves of the head.Ī) Structure present on the upper jaw: The upper jaws of frog are fixed or immovable. Mouth is a wide opening lies in between upper and lower jaw. Mouth:The digestive system of a frog starts with the mouth. The alimentary canal is a long, coiled path starts from mouth and ends in cloaca.It consists of organs such like mouth or buccal cavity, pharynx, esophagus,stomach, small intestine, large intestine and cloaca. The digestive system consists of the alimentary canal and digestive gland.
