The nervous system is an organ system in charge of sending messages to and from the brain and spinal cord to and from all parts of the body. It consists of the central nervous system and the peripheral nervous system. Another important part of the nervous system is the sense organs to which a special page is devoted.  Generation and specification of sensory organs. Histological studies 3 originally suggested that the different sensory organs of the chick inner ear are all derived from a single patch of cells in the ventromedial wall of the otocyst. A boundary model has been proposed to account for how the different sensory organs of the inner ear are specified 12. This model postulates that the different sensory organs of the inner ear form at, or in proximity to, the boundaries between a small number of different compartments. The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). Also housed within the inner ear are the semicircular canals, the utricle, and the saccule. These structures help control one’s sense of steadiness or balance. These balance organs share the temporal bone space with the cochlea. These organs also share the same fluid that is in These sensory organs of the inner ear are all derived during development from the wall of the otocyst, a hollow, pear-shaped structure that forms, just after neural tube closure, from a thickening of the head ectoderm that lies adjacent to the rhombencephalon and is known as the otic placode. A boundary model has been proposed to account for how the different sensory organs of the inner ear are specified 12. This model postulates that the different sensory organs of the inner ear form at, or in proximity to, the boundaries between a small number of different compartments. The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception.  There are six distinct sensory organs in the mammalian inner ear: the three cristae of the semicircular canals, the two maculae of the saccule and utricle, and the organ of Corti of the cochlea (Fig. 1). The cristae and the maculae are vestibular organs that respond to angular and linear acceleration, respectively. A boundary model has been proposed to account for how the different sensory organs of the inner ear are specified 12. This model postulates that the different sensory organs of the inner ear form at, or in proximity to, the boundaries between a small number of different compartments. Literature and acknowledgements. The nerve system, sensory organs and legs. Nervous system and sensory organs. There are two concentrations of ganglia in the prosoma (head-breast part or cephalothorax) which forms the brain. A number of nerves extends from the brain to the legs, eyes and the rest of the body. Sense Organs. There are five senses: sight, hearing, taste, smell and touch. There are organs connected with these sense that take in information that is sent to the brain so that the body can act on it. This carries the information to the occipital lobe of the brain where they are interpreted. Eyelids and eyelashes: These protect the eye and along with tears keep the eye clear and moist. Hearing. The ear is the organ concerned with hearing. The ear has three parts: the outer ear, the middle ear and the inner ear. Sensory organs. http://www.medicalook.com. SEARCH. Sensory organs are very highly developed and specialized organs that are an extension of the central nervous system, with a sole function to take in information and relate it to the brain. The brain’s interpretations of the sensations determined by the sensory system are called perception. Perception is the brain’s method of determining whether the information sent to the brain is pleasurable, painful, dangerous, or joyful. These perceptions explain to the body how to respond to the stimuli.
