A neuron transmits information by the secretion of hormones. True or False
grandymaker [24]

Answer:

The given statement is false.

A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.

The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).

The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.

VMariaS [17]
Taking a measure of someones blood glucose level before they eat in the morning is a measure of fasting blood glucose. A normal measure of fasting blood glucose is 3.8 to 5.5 mmol. If the value were higher, say 5.8 mmol then the patient would be described as being pre-diabetic. Since the value is the highest in the range of being normal she should be monitored for pre- diabetes.
