GENERAL HISTOLOGY

Detailed explanation-1: -Arthropods shed their exoskeletons as they grow, a process called ecdysis or moulting, and this behaviour is controlled by a set of hormones and small protein-like molecules called neuropeptides that allow communication between neurons.

Detailed explanation-2: -As the insect’s rigid exoskeleton cannot expand much, it must be shed and replaced with a larger one as the insect grows. This process is called molting. The life stage between each molt is called an instar. Molting is governed by hormones.

Detailed explanation-3: -To grow, arthropods must molt (shed) their exoskeletons periodically. During the molt, they form a larger exoskeleton to allow for expansion. The combination of an exoskeleton and jointed appendages is analogous to a suit of armor. The muscles for movement are attached to the inner surface of the exoskeleton Fig.

Detailed explanation-4: -Molting is the shed of old feathers to make way for new feathers. To keep itself in fine feather, a bird needs to molt each year to get rid of old or damaged feathers. Molting is required to renew a bird’s plumage and keep it in top condition.

Detailed explanation-5: -This shell provides protection for the animals, and gives support for the attachment of the arthropod’s muscles. Although arthropods grow, their exoskeletons do not grow with them. So they must periodically shed, or “molt” their exoskeletons in favor of a new one.
