Animal Tissues & Frog Anatomy — Common NEET Mistakes to Avoid — Summary

Cardiac muscle is NOT voluntary. The most common error is assuming all striated muscles are voluntary. Cardiac muscle is striated AND involuntary. Only skeletal muscle is striated AND voluntary.
Blood IS a connective tissue. Many students classify blood separately. It is a specialized connective tissue with plasma as the extracellular matrix.
Tendon ≠ Ligament. Tendons connect muscle to bone; ligaments connect bone to bone. Never swap these. Both are dense regular connective tissue, but ligaments contain elastin in addition to collagen.
Compound epithelium is NOT primarily for secretion or absorption. Its main function is protection. Only simple epithelium performs significant secretion and absorption.
Cartilage is avascular; do not confuse with bone. Cartilage lacks blood vessels and nerves (except at the perichondrium). Bone has blood supply via the Haversian canals.
Neuroglia ≠ Neurons. Neuroglia (Schwann cells, astrocytes, oligodendrocytes, microglia) are non-excitable support cells; they do not transmit impulses. Only neurons transmit electrical signals.
The frog has 10 cranial nerve pairs, not 12. Humans have 12 pairs. Frogs have 10. This numeric distinction is directly tested in NEET.
Frog heart has 3 chambers, not 4. A common trap is selecting 4 chambers (the mammalian answer). Frogs: 2 atria + 1 ventricle.
Intercalated discs are exclusive to cardiac muscle. Do not attribute them to skeletal muscle, even though both are striated.
Adipose tissue is loose connective tissue, not epithelium. Some students misclassify it due to its insulating and lining roles.
