Points on ear eye and brain of a frog.
Frogs rely on their vision and hearing to catch prey and avoid predators. They have good hearing and vision, although their ears and eyes aren't situated quite like those of most other animals. Frogs don't have external ears. Instead, they have an eardrum called the tympanum that sits just behind each eye. Often, you can see the eardrum -- it's a flat area surrounded by a ring of cartilage. In some species, scientists can tell whether a frog is male or female by comparing the size of the eardrums to the size of the eyes.
Most frogs have wide, bulging eyes that sit on the top of their skulls. This gives the frog a wide field of view and helps compensate for its inability to turn its head. There's not a lot of overlap between what a frog can see with its left eye and what it can see with its right, though. This may mean that frogs don't have as much depth perception as other animals do, which makes some species' ability to catch flying prey with their tongues even more amazing. Most frogs also have a nictitating membrane, or a sturdy film that covers and protects the eye while the frog is underwater.
The frog's brain is divisible into three parts namely:
Fore-brain: It consists of olfactory lobes, a pair of cerebral hemispheres, and unpaired diencephalon. Olfactory lobe of frog's brain controls the sense of smell.
Mid-brain: The mid-brain o fthe frog is consists of a pair of optic lobes. Optic lobes are invloved in the frog's vision.
Hind-brain: Hind-brain o fthe frog consists of cerebellum and medulla oblongata. Cerebellum helps to maintain the balance and equilibrium of the frog. The medulla oblongata passes out via the foramen magnum and continues into the spinal cord of the frog up to the tip of its trunk, which is contained in the vertebral column. Medulla oblongata helps in the regulation of respiration, digestion, and other automatic functions. Cerebellum also controls the muscular coordination and posture.
