Watch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve using some simple tests. The facial nerve controls the muscles of facial expression. Severe deficits will be obvious in watching someone use those muscles for normal control. One side of the face might not move like the other side. But directed tests, especially for contraction against resistance, require a formal testing of the muscles. The muscles of the upper and lower face need to be tested. The strength test in this video involves the patient squeezing her eyes shut and the examiner trying to pry her eyes open. Why does the examiner ask her to try a second time?
Every skeletal muscle fiber is supplied by a motor neuron at the NMJ. Watch this video (http://openstaxcollege.org/l/skelmuscfiber) to learn more about what happens at the neuromuscular junction. (a) What is the definition of a motor unit? (b) What is the structural and functional difference between a large motor unit and a small motor unit? Can you give an example of each? (c) Why is the neurotransmitter acetylcholine degraded after binding to its receptor?
Watch this video (http://openstaxcollege.org/l/nervsystem1) to learn more about the nervous system. As described in this video, the nervous system has a way to deal with threats and stress that is separate from the conscious control of the somatic nervous system. The system comes from a time when threats were about survival, but in the modern age, these responses become part of stress and anxiety. This video describes how the autonomic system is only part of the response to threats, or stressors. What other organ system gets involved, and what part of the brain coordinates the two systems for the entire response, including epinephrine (adrenaline) and cortisol?
Visit this site (http://openstaxcollege.org/l/nervetissue3) to learn about how nervous tissue is composed of neurons and glial cells. The neurons are dynamic cells with the ability to make a vast number of connections and to respond incredibly quickly to stimuli and to initiate movements based on those stimuli. They are the focus of intense research as failures in physiology can lead to devastating illnesses. Why are neurons only found in animals? Based on what this article says about neuron function, why wouldnt they be helpful for plants or microorganisms?
Figure 35.3 Which of the following statements is false? The soma is the cell body of a nerve cell. Myelin sheath provides an insulating layer to the dendrites. Axons carry the signal from the soma to the target. Dendrites carry the signal to the soma.
A _______________ is a drug that causes temporary paralysis by blocking the transmis- sion of nerve stimuli to the muscles. neuromuscular blocker skeletal muscle relaxant
Which of the following statements is true? Fast fibers have a small diameter. Fast fibers contain loosely packed myofibrils. Fast fibers have large glycogen reserves. Fast fibers have many mitochondria.
Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.
Neurons contain _____ which can receive_____ signals from other neurons. axons mitochondria dendrites Golgi bodies
Cytoplasmic extensions of _______ send and receive chemical messages. a. neuroglial cells b. neurons c. fibroblasts d. melanocytes
Brenda Farmers doctor could not find any physical changes to explain her symptoms. The doctor refers to this as a/an _________________ disorder.
Nerve impulses first stimulate a skeletal muscle fiber at _______. a. T tubules b. sarcomeres c. neuromuscular junctions d. actin binding sites
