Snake : Receptors – പാമ്പ്
The aromatic particles that stick on the tounge of the snake reach jacobson’s organ seen on the roof of the mouth cavity. The olfactory receptors seen there get stimulated then.
Shark : Receptors – സ്രാവ്
The lateral line is a series of sense organs located on both sides of the body of a shark. It is made up of a network of canals filled with sensory cells and can detect vibrations, pressure changes and movements of objects in the water surrounding the shark. It is used to sense prey and …
House fly : Receptors – ഈച്ച
The house fly (Musca domestica) has three simple eyes (ocelli) and two compound eyes. The compound eyes are made up of thousands of individual light-sensing units or ommatidia. Each ommatidium is made up of a cluster of 8-10 photoreceptor cells called retinula cells, which are connected to a nerve cell. Each ommatidium is separated from …
Planaria : Receptors -പ്ലാനേറിയ
Planaria possess an eye spot, which is a primitive light-sensing organ located in the anterior end of the organism. The eye spot is composed of a pigment cup containing light-sensitive cells that detect changes in light intensity. The eye spot is not really an eye, as it lacks a lens or other structures that would …
Receptors in the skin – ചർമ്മത്തിലെ റിസപ്റ്ററുകൾ
Receptors in the skin include temperature receptors, pressure receptors, pain receptors, and other specialized receptors such as those for itch, tickle, vibration, and proprioception. These receptors are embedded in the skin and signal the nervous system to respond to external stimuli. resapters, riceptors, reseptors
Detect smell – മണം തിരിച്ചറിയൽ
Process of detecting smell in sequential order Inhalation: The process of inhaling through the nose or mouth allows molecules of the odor to be drawn into the nasal cavity. Odorant Receptor Recognition: Odorant receptors in the olfactory epithelium recognize the odor molecules and send a signal to the olfactory bulb. Olfactory Bulb Activity: The olfactory …
Detect taste – രുചി കണ്ടുപിടിക്കാൻ
Chemoreceptors are sensory receptors that detect chemical changes in the environment and trigger a response in the body. Examples of chemoreceptors include taste buds, which detect the presence of sugars and other compounds in food, and olfactory receptors, which detect odours .Taste buds are sensory organs on the tongue that contain taste receptor cells, which …
Ear and balancing – ചെവിയും ബാലൻസും
Ear and balancing is the ability to keep your body in a stable position, and to detect and respond to changes in the orientation of your body. It involves the coordination of your eyes, inner ear, and the muscles and joints of your body. Good ear and balancing skills make it easier to stay upright, …
Hearing process – കേൾവി പ്രക്രിയ
The hearing process is a complex process that begins with the physical sound waves entering the ear. These sound waves travel through the ear canal and vibrate the eardrum. This vibration is transmitted to the ossicles (three small bones in the middle ear). The ossicles amplify the sound waves and send them to the cochlea. …
Cochlea – കൊക്ലിയ
The cochlea is a spiral-shaped organ within the inner ear of mammals and other vertebrates. It is responsible for converting sound waves into electrical signals that can be interpreted by the brain. The cochlea is divided into three distinct parts: the scala vestibuli, the scala tympani, and the cochlear duct. The entire structure is filled …
