The Nervous System edit) 1. The junction between one neuron and the next, or between a neuron and an effector is called: A) A synapse 8) A dendrite C) A neuotransmiter D ) A ventricle E) None of the above 2. A fast excitatory synapses follows this order A) (1) neurotransmiter released (2) diftused across the synaptic cleft to a receptor protein (3) binding of the transmitter opens pores in the ion channels and positive...
The most common form of reflex arc is the three-neuron arc, which consists of a sequence of neurons receiving sensory information, transmitting this information into the central nervous system for processing, and finally signalling muscles. What is the correct orderf neurons in such a reflex? unipolar- multipolar ntermeuron efferent- interneuron unipolar afferent+ interneuron bipolar efferent afferentinterneuron- Chemicals that cross over the synaptic cleft are called: electrical transmitters synaptic transmitters neurotransmitters chemotransmnitters D Bof 14 Critical thinking question 18.7 (p.407) ineffective...
For
each multiple choice, what is the answer and why?
5. Myelin A) is only found in the peripheral nervous system B) is secreted from the axon terminals of autonomic neurons. C) is a carbohydrate within the membranes of some neuroglia. D) is a chemical present in the plasma membrane of neurons. E) influences the rate of conduction of an electrical signal down an axon. 6. Which of the following organs/structures is (are) innervated by somatic motor nerves? (only ONE...
Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
A 35 year old female presents with a history of several episodes, each separated by several months, in which she experiences brief periods of physical weakness, clumsiness of the legs and hands, visual disturbances, and mood swings. Her weakness is most prominent in the lower extremities. CT scans show evidence of multiple lesions in the white matter of the brain and spinal cord. During her last episode, there were increasing neurological deficits due to an increasing number of disseminated lesions....
The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...
1. Nucleus * The point from which an activity or process is directed, or on which it is focused. Contains genetic information (DNA), controls the cell through production of mRNA and tRNA. The central and most important part of an object, movement, or group, forming the basis for its activity and growth. 2. Mitochondria * This is where aerobic respiration takes place to produce ATP as a form of energy the cell can use. An organelle found in large numbers...
