- Frogs possess a lengthy alimentary canal due to their carnivorous diet, aiding in the digestion of prey.
Rana Tigrina (Common Frog)
- Ten pairs of cranial nerves emerge from the frog's brain, facilitating various sensory and motor functions.
- Gaseous exchange occurs through lungs during aestivation, allowing the frog to survive in dry conditions.
- Red Blood Cells (RBCs) in frogs are enucleated, which is a characteristic of many amphibians.
- The forelimbs of frogs end in four digits, aiding in locomotion and jumping.
Incorrect Statements Regarding Rana Tigrina
- Frogs are classified as ureotelic, excreting urea instead of ammonia.
- The vascular system of frogs is closed, contrary to the misconception of it being open.
- Pancreatic juice is primarily responsible for the digestion of carbohydrates in frogs and should not be confused with other functions.
Tissue Identification
- Adipose tissue is found beneath the skin, acting as insulation and energy storage.
- Cartilage provides structural support and flexibility, not located beneath the skin.
- Ligaments connect bones at joints, while tendons connect muscles to bones.
Blood Composition
- Blood comprises four primary components: Red Blood Cells (RBCs), White Blood Cells (WBCs), platelets, and fibre secreting cells that aid in clotting.
Neuronal Activity
- Neurons can trigger either stimulation or inhibition in adjacent neurons when they receive disturbances at their endings, crucial for nervous system functioning.
Modified Polysaccharides Secretion
- The specific entities secrete modified polysaccharides; know the options provided to identify the correct source.
Identifying Correct Statements
- Analyze the statements about blood composition and neuronal function to determine their accuracy and relevance.
- Correct understanding of anatomical and physiological traits is fundamental for biology studies, particularly in amphibians.
