On a human body, dorsal (i.e., posterior) refers to the back portion of the body, whereas ventral (i.e., anterior) refers to the front part of the body. … For example, the stomach is ventral to the spinal cord, which means that the stomach is located in front of the spinal cord.

What do nuptial pads look like?
Nuptial pads are patches of thickened skin, associated with sexually dimorphic skin glands, present only in the thumbs and fingers of male anurans, and hence considered dimorphic sexual characters. Despite the morphological description for many species, the evolution and function of nuptial pads are still unclear.
Where is the shank on a frog?
Crus or shank (lower leg) is the section of hind limb or leg between the knee and foot of the frog. It is more distal to main body and hence helps the frog to move.

What are the forelimbs of frog?
Once again, note that the forelimbs of the frog consist of two stout bones – a proximal humerus (1) and a distal radioulna (2). The hand is composed of a number of carpals (3), metacarpals (4) and distal elements called phalanges (5). The forelimbs are supported by a number of bones that make up the pectoral girdle.
What are the 3 main parts of the forelimb?
The forelimb consists of: Humerus, radius and ulna, carpals, metacarpals, digits or phalanges (see diagram 6.6). The top of the humerus moves against (articulates with) the scapula at the shoulder joint. By changing the number, size and shape of the various bones, fore limbs have evolved to fit different ways of life.
What kinds of forelimbs are there name two?
- Nonopposable thumbs: tarsiers and marmosets.
- Pseudo-opposable thumbs: all strepsirrhines and Cebidae.
- Opposable thumbs: Old World monkeys and all great apes.
- Opposable with comparatively long thumbs: gibbons (or lesser apes)

What are the respiratory organs of amphibians?
Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).
Why are amphibians called amphibians?
All amphibians spend part of their lives in water and part on land, which is how they earned their name—“amphibian” comes from a Greek word meaning “double life.” These animals are born with gills, and while some outgrow them as they transform into adults, others retain them for their entire lives.
