Frogs have a highly developed nervous system that consists of a brain, spinal cord and nerves. Many parts of frog brains correspond with those of humans. It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata.
Not all animals have neurons; Trichoplax and sponges lack nerve cells altogether. Neurons may be packed to form structures such as the brain of vertebrates or the neural ganglions of insects. The number of neurons and their relative abundance in different parts of the brain is a determinant of neural function and, consequently, of behavior.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
Female grey foam-nest tree frogs lay eggs which are quickly fertilized by the male soon afterwards. Females also create foam for nests. [ 5 ] Grey foam-nest tree frogs show remarkable adaptability in their oviposition sites, as they may lay their eggs in a variety of unique habitats.
The hole-in-the-head frog (Huia cavitympanum) is a species of frog in the family Ranidae.It is the only member of the genus Huia. [2] It is found on the island of Borneo.Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and torrential rivers.
“They start out small, but they can quickly grow as big as your hand,” said Sollenberger. “It's a really big tree frog. They can get three times the size of our next largest native tree frog ...
Specifically, he identified two main regions of the brain, the tectum and the thalamic-pretectal region, that were responsible for discriminating prey from non-prey and revealed the neural pathways that connected them. Furthermore, he found that the neural mechanisms are plastic and adaptable to varying environments and conditions (Carew 2000 ...
Paleontologists have discovered a previously unknown ancient species: Kermitops — an amphibian that predates the dinosaurs and reveals the complexity of frog evolution. Researchers found a tiny ...
