Frog body parts and functions essay

The head of humerus fits into the glenoid cavity.

When it is completely empty, it shrinks. Gall Bladder - Sac which stores bile.

Glottis function frog

The anterior, vertical and horizontal canals bear the ampullae at their anterior ends while the posterior vertical canal contains an ampulla each at its posterior end. All the transverse collecting tubules lead into the ureter urinogenital duct. Sense Organs of Frog: Frog has five types of sense organs: i Tango receptors organs of touch : These are nerve endings and touch corpuscles which are found in the skin. Now… on to my topic Tadah! Presentation on theme: "Frog Body Parts and Functions. These are connected with the central nervous system after travelling in some cranial and spinal nerves. It also takes part in the formation of brachial plexus. Each is made up of a cell body and fibers of varying lengths. Body Structure Similarities Although each may look quite different, frogs and humans have skin, bones, muscles and organs. During hibernation, thefrog needs little oxygen and no more food than is alreadyin it's tissues. On the whole, their organ structure is similar, but frogs have considerably less complex anatomies. On stimulation, the parasympathetic nerve fibres secrete a chemical called acetylecholine, whose function is just opposite to that of sympathin. Internal ear: It is lodged in the bony auditory capsule, which is mainly formed by prootic bone, whose cavity contains a watery fluid, the perilymph. Since the eyes of frog are situated one on each side of the head, each eye focuses its own object and both the eyes cannot focus on one object, this type of vision is known as monocular vision. Secretin causes the release of sodium bicarbonate solution from the pancreas for pancreatic juice and from the liver for bile cholecystokinin stimulates the gall bladder to release the bile into the duodenum.

Due to the contraction of radial muscles the diameter of the pupil is increased and by the contraction of circular muscles the diameter of the pupil is decreased. They carry impulses from the skin receptors to the spinal cord and from the spinal cord to the muscles.

Nerves - Bundles of neurons fibers which transmit messages. Males and females of each species have testes and ovaries respectively.

Frog kidney function

Common Bile Duct - Tube which carries bile from the gall bladder and digestive juice from the pancreas into the duodenum. Hemoglobin - The red pigment in red blood cells which combine with and carry gases. Thymus: The thymus in the adult frog is a small compact lymphoid body located behind each tympanum under the depressor mandibulae muscle. The stapes lies over a small oval aperture, the fenestra ovalis. During the breeding season, the wall of the ovary ruptures to release the ova into the coelom. Cloacal Opening - Opening of cloaca through which undigested food, urine, eggs, and sperm are passed. Development is indirect involving a larval stage called tadpole. It is much smaller in the adult than in the tadpole. Olfactory Lobe - Part of the frogs brain associated with the sense of smell Cerebrum - Part of the brain that is associated with memory, pain, and voluntary muscle control. It can undergo periodic contractions due to the presence of un-striped muscles. In higher vertebrates like mammals, the adrenal gland consists of distinct outer cortex and inner medulla. During hibernation, thefrog needs little oxygen and no more food than is alreadyin it's tissues. It is also involved in purposeful acts such as creativity, judgment, problem solving, and planning.

A hind limb comprises femur, tibio- fibula, tarsals, metatarsals and five digits. The fat bodies store the food material specially for hibernation period.

Excretory System of Frog: The excretory system in both male and female frogs is similar except a few minor differences.

What is the function of the gallbladder in a frog

Peritoneum covers each kidney only on its ventral surface. Optic Lobes - Part of the brain associated with vision. The four muscles are recti, namely, superior rectus, inferior rectus, internal rectus, external rectus and two oblique muscles: superior oblique and inferior oblique. Gullet - Posterior part of the mouth cavity in a frog. This all happens due to the pressure exerted by the fore-limbs of male on the body of the female frog during amplexus the clasping of the female frog by the male frog before discharging sexual products in water is called amplexus, and by the beating of cilia present in the internal epithelial lining of the oviduct. The head of both frogs and humans contains the brain, mouth, eyes, ears and nose. Each urinogenital duct runs posteriorly, and before opening into cloaca, it dilates to form a seminal vesicle to store the sperms temporarily. Thin narrow tube, the ductus endolymphaticus, arises from the sacculus and enters the cranium brain box to form a thin walled sac, the endolymphaticus sac over the hind-brain. Pancreas - Gland which secretes digestive enzymes into the duodenum. Although frogs, as adults, inhale and exhale through the mouth only while humans inhale and exhale through the mouth and nose , the internal organs involved in the respiratory process function in much the same way.
