The proximal end is also the site from which the new centriole is built, using the cartwheel, which consists of a hub at the centre and nine spokes, each contacting the A-tubule of a triplet microtubule to organize assembly. Within the centriole’s centre and distal end is a luminal density.Read More →
A soft iron core is used in galvanometer because the magnetic lines of force can be attracted by the soft iron core. This attraction of magnetic lines of force increases the magnetic field which increases the sensitivity of galvanometer. Why soft iron is used in moving arm in motor? insteadRead More →
Most echinoderms show pentamerous radial symmetry, five equal segments radiating from a central body. Unique to their phylum, echinoderms possess a water vascular system, a network of water-filled canals that along with muscular extensions called podia (tube feet) allow these organisms to move around the seafloor. What kind of symmetryRead More →
Your treatment depends on how bad the break is. Your doctor may have put your arm in a cast or splint to allow your elbow to heal or to keep it stable until you see another doctor. You also may wear a sling to help support your arm. It mayRead More →
Normal: Pulse is symmetrical, regular and between 60-90 per minute. You have to learn to appreciate the character and amplitude of the normal pulse. Where does radial pulse occur? Your radial pulse can be taken on either wrist. Use the tip of the index and third fingers of your otherRead More →
Extensor carpi radialis longus. Extensor carpi ulnaris. What is innervated by the radial nerve? The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb. It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as wellRead More →
Sponges have asymmetrical symmetry. When an animal’s body shape is asymmetrical, there is no axis or line that can be drawn where it is essentially… Why do sponges not have symmetry? Unlike Protozoans, the Poriferans are multicellular. However, unlike higher metazoans, the cells that make up a sponge are notRead More →
Most deuterostomes display indeterminate cleavage, in which the developmental fate of the cells in the developing embryo is not determined by the identity of the parent cell. … In deuterostomes the mesoderm forms as evaginations of the developed gut that pinch off to form the coelom. This process is calledRead More →
