The structure and function of a chemical synapse. Given: Before an action potential moves into the next neuron, it crosses a tiny gap between the neurons called a synapse. Introduction: The junction point between the axon terminal of one neuron (presynaptic neuron) and the dendrites of the adjacent neuron (post synaptic neuron) is called as synapse. The synapses ensure the unidirectional transmission of nerve impulse conduction. The chemical transmission across the synapse was discovered by Henry Dale (1936). In the synapse between neurons chemicals signals called neurotransmitter was released by the presynaptic neuron which binds to the receptors of the post synaptic neuron. This will cause the sodium channel to open generating an action potential in that neuron.

I’m struggling with this topic and would really appreciate your help. I need to hand-draw a diagram and explain the process of sexual differentiation in humans, including structures, hormones, enzymes, and other details. Could you also make sure to include these terms in the explanation? • Gonads • Wolffian ducts • Müllerian ducts • Testes • Testosterone • Anti-Müllerian Hormone (AMH) • Epididymis • Vas deferens • Seminal vesicles • 5-alpha reductase • DHT • Penis • Scrotum • Ovaries • Uterus • Fallopian tubes • Vagina • Clitoris • Labia Thank you so much for your help!

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.
