Mineral found in red pigment of vertebrate blood is
Red pigment of vertebrate blood is haemoglobin. Haemoglobin is a conjugated protein. It consists of a basic protein globin joined to a nonprotein group heme, hence the name haemoglobin. Heme is an iron-porphyrin ring. A mammalian haemoglobin molecule is a complex of 4 heme molecules joined with 4 globin molecules.
The process by which bone formed is known as:
The contractile protein of skeletal muscle involving ATPase activity is
Which of the following acts as antibody to help in body defence?
Immunoglobulin A (IgA), as the principal antibody class in the secretions that bathe these mucosal surfaces, acts as an important first line of defence. IgA, also an important serum immunoglobulin, mediates a variety of protective functions through interaction with specific receptors and immune mediators. The importance of such protection is underlined by the fact that certain pathogens have evolved mechanisms to compromise IgA-mediated defence, providing an opportunity for more effective invasion. IgA function may also be perturbed in certain disease states, some of which are characterized by deposition of IgA in specific tissues. This review details current understanding of the roles played by IgA in both health and disease.
Smooth muscle is found in all the sites except:
In a neuron, dendrite may be one or many, but axon is generally:
A tissue is made up of:
Which one of the following cellular components of the blood is responsible for the production of antibodies?
Which of the following is present in the alveoli of lungs?
This one is the characteristic of epithelial tissue:
Blood plasma is:
Which of the following is a transparent tissue?
Lacuna of bone contains:
Major protein of connective tissue is:
Light bands of muscle fibre are made of the protein:
Canaliculi are found associated with:
Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. Osteocytes do not entirely fill up the canaliculi.
Processes from osteoblasts are found in :
The bone marrow is composed of :
The longitudinal canals of the bone are called :
Volkmann's canals occur in :-
