In contrast to the hindlimbs, the forelimbs are generally considered to be conserved among frogs. Their main function is thought to be associated with providing body support during sitting or walking, and/or the absorption of impact forces during landing (Nauwelaerts & Aerts, 2006).

What are forelimbs used for?
Their forelimbs are used for both short sprints and grappling, which means that they need to be flexible and durable. In contrast, canids, which often pursue their prey over greater distances, have longer, more gracile limbs.
What kind of limbs can a frog forelimb?
The hindlimbs of humans are capable of walking, running, jumping etc. while the hindlimbs of frogs are muscular and allow jumping and swimming. Such organs that are similar in structure in two different species but are performing unrelated functions are called homologous organs.
How are forelimbs different from hind limbs?
Forelimbs are the ones that are found in the front part of the body i.e arms. Hind limbs are those that are found in the back part of the body I.e legs. ... Fore limbs are shorter than the hind limbs. This is due to taller bones present in the hind limbs as compared to fore limbs.
How many forelimbs does a frog have?
However, although the two forelimbs emerge abruptly and fully formed, their emergence is asymmetric (Malashichev 2002).
What is the definition of forelimb?
Definition of forelimb
: a limb (such as an arm, wing, fin, or leg) that is situated anteriorly the forelimb of a bat.
What animals have a forelimb?
Humans, whales, bats, eagles, lizards, frogs and chimpanzees are very different types of animals that use their forelimbs in very different ways. But beneath the skin, the forelimb bones of these animals are startlingly similar.
What is the function of the Nictitating membrane in a frog?
In amphibians, nictitating membranes provide a layer of protection during activities such as swimming, resting, or handling prey. The membranes are usually translucent, so the animals are still able to see to some degree even when their third eyelids are deployed.
What is the function of the tympanic membrane in a frog?
Amphibians like frogs, some reptiles and many insects use this protective circular patch of skin stretched over a ring of cartilage (just like a drum) to transmit sound waves to the middle and inner ear for interpretation by the brain. For a frog, the tympanum allows it to hear both in the air and below the water.
What kind of limbs are in frog forelimb and human hand?
Therefore, the structures that are similar in structure of two organisms but have different functions are termed as homologous organs. Hence, the correct answer is 'A'. Homologous organs.
Why do frogs have larger hind limbs than forelimbs?
Because the frog's habitat relies on these kinds of movement, the back legs have developed to be much larger than the front legs. Water-loving frogs have muscular back legs with large feet so they can perform big jumps and swim quickly.
How do birds use their forelimbs?
The forelimbs (front legs) of birds are modified into wings. ... They provide the powerful wing strokes that are essential for flight. The muscles under the pectorals raise the wings between wing beats. Together, these flight muscles make up about 25 to 35% of the bird's full body weight.
Why are forelimbs of birds modified?
Forelimbs of birds are modified into wings that help them to fly. These wings exert a downward force that helps the birds to lift up.
What is Mesorchium in frog?
Mesorchium is a thin mesentery that suspends testis from ventral anterior part of kidney. ...
Where do you find the axillary regions of the frog?
The axillary region is the area between the superior portion of the upper limb and the thorax.
What makes up the sternum of the frogs?
Sternum. Examine the sternum in the different classes, notice that in Amphibia like Salamanders it is of cartilage, in Frogs cartilage and bone, and attached to the pectoral girdle only. It acts as a skid and is not attached to the short ribs.
