Asymmetric synapses, which are excitatory in function, predominate and account for about 80% of the total population of synapses. Asymmetric synapses are formed by axon terminals that contain spherical synaptic vesicles. The synaptic junction has a rather wide cleft and an obvious postsynaptic density.
Capsicum, also known as red pepper or chili pepper, is an herb. The fruit of the capsicum plant is used to make medicine. Capsicum is used for various problems with digestion including upset stomach, intestinal gas, stomach pain, diarrhea, and cramps. It is also used for conditions of the heart and blood vessels including poor circulation, excessive blood clotting, high cholesterol, and preventing heart disease.
Capsaicin (pronounced cap-SAY-a-sin) is the chemical in chili peppers that makes them spicy. Specifically, capsaicin occurs in the fruits of plants in the Capsicum family, including bell peppers, jalapeÃ±o peppers, cayenne peppers and other chili peppers. Capsaicin in chili peppers is measured on the Scoville Scale and expressed in terms of Scoville Heat Units. Bell peppers are the only member of the capsicum family that don't contain capsaicin, and thus register zero Scoville units.
