During the process of muscle damage, explain the process of HPA axis activation starting with what activates the hypothalamic secretions.
HPA axis has a activation system which involves number of neurons and also endocrine systems.In those Glucocorticoids play an important role i the activation of HPA axis.So the paraventricular nucleus of hypothalamus secrete vasopressin and corticotropin releasing hormone.
During the process of muscle damage, explain the process of HPA axis activation starting with what...
activation of the hpa axis allows the body to
e HPA axis involves the initial activation of the: a. hypothalamus b. hindbrain 18. Th c.hippocampus d. heart 19. Each of the following is the result of activation of the sympathetic nervous system in response to a stressor EXCEPT: a. heart rate increases b. pupils dilate c. breathing becomes more rapid d. muscle tension decreases ??20. In humans, the alarm stage of the general adaptation syndrome involves: a. the inhibition of the hypothalamic-pituitary-adrenal system b. the production of cortisol, which...
Discuss how glucocorticoid negative feedback suppresses the hypothalamic pituitary adrenal axis (HPA) for the suppression of the stress axis with a reference to experimental evidence. Your answer should include discussion of the receptor signaling pathways glucocorticoids signal through, the time course of action and the cellular functions which are altered following glucocorticoid receptor activation.
Describe the process of B cell activation starting with antigen binding to IgM.
Explain the mechanism of skeletal muscle stretch reflex, highlighting alpha-gamma co-activation and involved structures.
Explain the basic process of PCR. Include: what starting materials are required and what each of them does, tell me each of the steps in the PCR cycle and what the purpose is for each.
What is the smallest functional unit of skeletal muscle? Explain why it is the smallest functional unit and what happens to it during muscle contraction.
1. Explain the steps involved in muscle contraction starting from stimulation of the sciatic nerve (somatic motor neuron) to contraction of the muscle fibers within the gastrocnemius. Be sure to include any movements of ions, neurotransmitters, myofilaments and other relevant structures/particles in your answer. (3 pts) 2. Why do we see a graded response (tension increasing) in single muscle twitch when increasing the voltage (strength) of the stimulus that is applied? Was there a point at which maximal tension was...
