例句 | An olfactory receptor neuron, also called an olfactory sensory neuron, is the primary transduction cell in the olfactory system. Fundamentals of Biology 2015-01-01T00:00:00Z Each olfactory sensory neuron has only one type of receptor on its cilia, and the receptors are specialized to detect specific odorants, so the bipolar neurons themselves are specialized. Biology for AP Courses 2022-06-09T00:00:00Z For example, the sight, smell, and taste of food initiate long reflexes that begin with a sensory neuron delivering a signal to the medulla oblongata. Anatomy and Physiology 2013-06-19T00:00:00Z Further receptor-deletion experiments strongly suggested that previously documented changes3,4 in two other key classes of sensory neuron are also involved. How a fly came to love the vomit fruit 2020-03-03T05:00:00Z Skin’s somatosensory system comprises more than a dozen subtypes of sensory neuron, but only those involved in tactile sensation are well understood. Superpowered skin 2018-11-20T05:00:00Z This single protein molecule can respond to both heat and capsaicin by opening an ion channel, a pore that lets positive ions flow inside, thereby causing the sensory neuron to fire electrical spikes. How We Sense the Heat of Chili Peppers and the Cool of Menthol [Excerpt] 2015-02-04T05:00:00Z For example, the knee reflex that a doctor tests during a routine physical is controlled by a single synapse between a sensory neuron and a motor neuron. Biology for AP Courses 2022-06-09T00:00:00Z This occurs when a stimulus changes the cell membrane potential of a sensory neuron. Anatomy and Physiology 2013-06-19T00:00:00Z The answer lies in a particular type of sensory neuron that responds to pleasant stroking, say scientists at the California Institute of Technology in Pasadena. Mice Have 'Massage Neurons' 2013-01-30T21:45:03.993Z When that second mutation, in a sensory neuron gene previously linked to longevity, was bred out, they found no evidence that boosted lifespan. Longevity Genes Challenged by New Data Showing No Extension of Lifespan 2011-09-21T21:45:00.210Z A free nerve ending, as its name implies, is an unencapsulated dendrite of a sensory neuron. Biology for AP Courses 2022-06-09T00:00:00Z The sensory neuron cell bodies are grouped in structures called dorsal root ganglia and are shown in Figure 26.29. Biology for AP Courses 2022-06-09T00:00:00Z Each olfactory sensory neuron has dendrites that extend from the apical surface of the epithelium into the mucus lining the cavity. Anatomy and Physiology 2013-06-19T00:00:00Z When an odorant binds with a receptor that recognizes it, the sensory neuron associated with the receptor is stimulated. Biology for AP Courses 2022-06-09T00:00:00Z When the hairs bend, they release an excitatory neurotransmitter at a synapse with a sensory neuron, which then conducts action potentials to the central nervous system. Biology for AP Courses 2022-06-09T00:00:00Z However, generator potentials can initiate action potentials in the sensory neuron axon, and postsynaptic potentials can initiate an action potential in the axon of other neurons. Anatomy and Physiology 2013-06-19T00:00:00Z Each sensory neuron has one projection—with a sensory receptor ending in skin, muscle, or sensory organs—and another that synapses with a neuron in the dorsal spinal cord. Biology for AP Courses 2022-06-09T00:00:00Z The interneuron receives a synapse from the axon of the sensory neuron that detects that the hand is being burned. Anatomy and Physiology 2013-06-19T00:00:00Z A simple case is a reflex caused by a synapse between a dorsal sensory neuron axon and a motor neuron in the ventral horn. Anatomy and Physiology 2013-06-19T00:00:00Z Somatic reflexes always involve the CNS, even in a monosynaptic reflex in which the sensory neuron directly activates the motor neuron. Anatomy and Physiology 2013-06-19T00:00:00Z A sensory neuron can project to the CNS or to an autonomic ganglion. Anatomy and Physiology 2013-06-19T00:00:00Z Disturbance of these dendrites by compressing them or bending them opens gated ion channels in the plasma membrane of the sensory neuron, changing its electrical potential. Biology for AP Courses 2022-06-09T00:00:00Z In response to this stimulation from the sensory neuron, the interneuron then inhibits the motor neuron that controls the triceps brachii. Anatomy and Physiology 2013-06-19T00:00:00Z The short reflex involves the direct stimulation of a postganglionic fiber by the sensory neuron, whereas the long reflex involves integration in the spinal cord or brain. Anatomy and Physiology 2013-06-19T00:00:00Z If a sensory neuron projects directly to the ganglionic neuron and causes it to activate the effector target, then the CNS is not involved.
