Answer» STEM ACADEMIA AGRICULTURE & FARMING HUMANITIES SOCIAL SCIENCES\xa0 \xa0\tOwlcation»\tSTEM»\tMedical ScienceReflex Action and Reflex Arc: What Happens When You Accidentally Touch a Hot PotUpdated on August 6, 2017Edmund Custers\xa0 \xa0more Contact AuthorReflex action and reflex arc when a cook touched a hot pot by accident\xa0\|\xa0SourceReflex Action and Reflex ArcReflex is a special ability that evolution gifted us to facilitate our survival. Whenever part of your body comes in contact with an object capable of causing you harm, you tend to quickly withdraw that part of the body. This happens before your brain gets the time it needs to process the threat.Reflex ActionIf you accidentally touch a hot pot on your stove while cooking, you would involuntarily (and nearly instantaneously) snatch your hand away from the pot. This response is called a ‘reflex action\'.Reflex ArcContact with the hot pot triggers the start of a series of events in the body to evoke a response.At the point of contact with the hot pot, skin receptors quickly send nerve impulses (electrical) to the spinal cord (central nervous system) via sensory neurons. In the spinal cord, the impulses are processed and a response is relayed back.In the spinal cord, the interneurons (also known as relay neurons) make the connections between the sensory neurons (bringing the message from hand) and the correct motor neurons (taking the response back to the hand). It would be not be useful if the response was sent to the wrong part of the body—in this case, a response sent to the leg wouldn\'t be too helpful as the stimulus is coming from the hand.From the interneurons, the response is relayed to the motor neurons which project out of the spinal cord to stimulate your muscles (effector) to contract, causing you to snatch your hand away from the hot pot. This pathway taken by nerve impulses to elicit a response is known as a ‘reflex arc’.This process happens so fast that the response occurs before the message reaches the brain. This results to a quicker time-to-response as the thinking process of the brain may be relatively time consuming.

Answer» Muscle contraction\xa0is the activation of tension-generating sites within\xa0muscle\xa0fibers. In physiology,\xa0muscle contraction\xa0does not necessarily mean\xa0muscle\xa0shortening because\xa0muscle\xa0tension can be produced without changes in\xa0muscle\xa0length such as holding a heavy book or a dumbbell at the same position.

Answer» Histology is the study of the microscopic anatomy of cells and tissues of plants and animals. It is commonly performed by examining cells and tissues under a light microscope or electron microscope,r electron microscope, the specimen having been sectioned (cut into a thin cross section with a microtome), stained, and mounted on a microscope slide.

3466.	About anemia
Answer» Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen. Symptoms of anemia -- like fatigue -- occur because organs aren\'t getting what they need to function properly.

3463.	What translocation
Answer» The movement of something from one place to another.

3470.	What is semi permeable membrane
Answer» A\xa0semipermeable membrane\xa0is a type of biological or synthetic, polymeric\xa0membrane\xa0that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

3471.	Were live erthworm
Answer» In soil for example:farm Bathroom?

3473.	What do you mean by meiosis
Answer» The type of cell division in which in which the chromosome number become half and cell divides twice

3475.	Dentition?
Answer» The process of appropriate arrangement or condition of the teeth in a particular species is called Dentition.

3476.	Describe meiosis 1 and meiosis 2 stage with labelled diagram
Answer»

3479.	If the tidal volume is about 500ml then which value is written about 6000-8000 ml in ncert book
Answer»

3480.	Describe the process of digestion of protein in stomach
Answer» Pepsin is the active protein-digesting enzyme of the stomach. Pepsin acts on protein molecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase.

3481.	What is nodule formation?
Answer» Root nodules that occur on non-legume genera like Parasponia in association with Rhizobium bacteria, and those that arise from symbiotic interactions with Actinobacteria Frankia in some plant genera such as Alnus, vary significantly from those formed in the legume-rhizobia symbiosis.

3482.	What is polypeptide
Answer» a linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule. It is chain of protiens bonded together by peptide bonds llinked to form a linear, secondary,tertiary,quaternery structure.

3494.	Nail are death cells so ,why it\'s grows
Answer» Nails and hair are essentially made up of a tough protective protein called keratin. While the hair grows in a hair follicle, nails grow from the matrix (the base of the nail bed). Both the hair follicle and the nail matrix are made of epithelial cells and will continue to grow as long as they receive nutrition and remain healthy. As the epithelial cells within the follicle and matrix multiply, the older cells are pushed out, upwards through your skin. They die and harden, thus turning into hair or nails. This process, called keratinisation, makes your hair and nails grow.
