Watch this video (http://openstaxcollege.org/l/basalnuclei1) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the direct pathway is the shorter pathway through the system that results in increased activity in the cerebral cortex and increased motor activity. The direct pathway is described as resulting in disinhibition of the thalamus. What does disinhibition mean? What are the two neurons doing individually to cause this?
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/troublewstairs) to read about a woman that notices that her daughter is having trouble walking up the stairs. This leads to the discovery of a hereditary condition that affects the brain and spinal cord. The electromyography and MRI tests indicated deficiencies in the spinal cord and cerebellum, both of which are responsible for controlling coordinated movements. To what functional division of the nervous system would these structures belong?
Watch this video (http://openstaxcollege.org/l/emotions) to learn about physical responses to emotion. The autonomic system, which is important for regulating the homeostasis of the organ systems, is also responsible for our physiological responses to emotions such as fear. The video summarizes the extent of the bodyâ€™s reactions and describes several effects of the autonomic system in response to fear. On the basis of what you have already studied about autonomic function, which effect would you expect to be associated with parasympathetic, rather than sympathetic, activity?
Some survivors of disastrous events have post-traumaticstress disorder (PTSD). Symptoms include nightmaresabout the experience and suddenly feeling as if the eventis recurring. Brain-imaging studies of people with PTSDshowed that their hippocampus was shrunken and theiramygdala unusually active. Given these changes, whatother brain functions might be disrupted in PTSD?
The ____ receives a large amount of information from the amygdala. It's the final destination for most of the brain's information about emotion before action is taken. For this reason, patients with damage to this region often struggle to make decisions, especially when those decisions involve avoiding risks or learning from reinforcement and punishment. A) ventromedial prefrontal cortex B) posterior parietal cortex C) anterior insular cortex D) anterior cingulate gyrus
Memory, emotional, language, and sensorimotordeficits together are most likely the result of what kind ofdamage?a. strokeb. developmental disorderc. whiplashd. gunshot wound
The part of the diencephalon that regulates hunger,weight, water and electrolyte balance, sleep andwakefulness, temperature, arterial blood pressure,heart rate, production of substances that stimulatethe pituitary gland, and movement and secretion inareas of the digestive tract is the .a. thalamusb. pineal glandc. infundibulumd. hypothalamus
The ______ controls most of the autonomic nervous system functions and is considered the main integration center for the autonomic nervous system (ANS). It is located in the __________. Group of answer choices thalamus;diencephalon subcortical nuclei;basal nuclei pituitary gland;brain stem hypothalamus;diencephalon
Which of these structures is not under direct control ofthe peripheral nervous system?a. trigeminal ganglionb. gastric plexusc. sympathetic chain gangliad. cervical plexus
The autonomic portion of the PNS functions _________.a. consciouslyb. voluntarilyc. without conscious effortd. dependently
What function would most likely be affected by arestriction of a blood vessel in the cerebral cortex?a. languageb. gaitc. facial expressionsd. knee-jerk reflex
