Morphology of Frogs
Though larvae have tails, adult frogs are tailless. An adult frog has a stout body which is differentiated into head and trunk. Other external features are a pair of nostrils, protruding eyes, a membranous tympanum (ear), slippery/warty moist skin and webbed limbs.
What is the body parts of frog?
Organs. Frogs possess a liver, heart, lungs, stomach, gall bladder and intestines. These organs perform the same functions for the frog as they do in human bodies: The heart pumps blood throughout the body, and the lungs aid in breathing.
Which of the following sensory structures are well organized in the frog?
Frog has different types of sense organs, namely organs of touch (sensory papillae), taste (taste buds), smell (nasal epithelium), vision (eyes) and hearing (tympanum with internal ears). Out of these, eyes and internal ears are well-organised structures and the rest are cellular aggregations around nerve endings.
Does a frog have claws?
The frogs defend themselves with sharp bone claws on their hind feet but to do so, the animals have to drive the claws through their own skin. ... Two genera in particular – Astylosternus (the night frogs) and Trichobatrachus (the hairy frog) – have well developed claws on eight of their hind toes.
Is a frog a vertebrates?
Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts.
Where is the trunk of a frog?
Trunk: central part of a frog, to which are attached the head and limbs.
Do amphibians have claws?
Amphibians do not have hair, feathers, or claws. ... Amphibians can be divided into three groups - frogs and toads, salamanders and newts, and caecilians [pronounced sesil´eens]. Scientists have found over 4000 species of amphibians.
Are frog bones hollow?
The bones are hollow and lightweight. The musculoskeletal system is strong to enable it to support the head and body. The bones are fully ossified and the vertebrae interlock with each other by means of overlapping processes.
What are the 3 parts of the small intestine in a frog?
Small Intestine - The principal organ of digestion and absorption of digested food. Duodenum - The anterior (front) part of the small intestine into which food passes from the stomach. Pancreas - Gland which secretes digestive enzymes into the duodenum. Gall Bladder - Sac which stores bile.
What is the top part of a frog called?
Our frog can be divided into the dorsal, or top side, and the ventral, or bottom side.
Where is the medial on a frog?
Anatomical Terms: Medial: Toward the midline. Proximal: Lying near to. Distal: Lying away from.
What are the sensory structures related to the forebrain of a frog?
Forebrain: It consists of two olfactory lobes, two cerebral hemispheres and a diencephalon. Olfactory lobes: ... Olfactory lobes are concerned with sense of smell which is poorly developed in frog.
What is frog movement?
The methods by which the animal moves around is through jumping, swimming, gliding, and burrowing. The hind limbs of frogs are muscular and strong and help in hopping long distances. And the webbed feet also help them in swimming.
Do frogs have gills?
When a frog egg hatches, a wiggly tadpole emerges that can live only in water. It breathes through gills. ... Their gills absorb oxygen directly from the water in which they swim, releasing waste carbon dioxide at the same time. As they mature, the gills are slowly absorbed, and primitive lungs begin to develop.
