Answer:
Endocrine system regulates D Hormonal and glandular secretion.
Explanation:
Endrocrine system composed of various glands that secrete hormones or chemical messengers. Those glands include Pituitary gland,Thyroid gland, Adrenal gland etc.
These glands are well known for secretion of various hormones those regulate various physiological activities of our body.
For example Anterior lobe of pituitary gland secretes growth hormones which stimulates the growth of various body parts of our body.
Thyroid hormone secretes T3 and T4 that regulates basal metabolic rate, body temperature, oxygen consumption and also iodine utilization.
Adrenal cortex secretes Glucocorticoid hormone that helps to regulate the blood glucose level as well Protein Metabolism of our body.
Answer:
1. The presynaptic neuron reaches the synaptic knob and the terminal is depolarized.
2. The electrical voltage gated calcium channels in the presynaptic knob opens.
3. The calcium ions enters through the calcium channel, this calcium ions cause the fusion of the synaptic vesicles to the presynaptic membrane, the cell membrane of an axon terminal that faces the receiving cell.
4. There is neurotransmitter release by the axon terminal of a neuron and bind to and react with the receptors on the dendrites of another neuron e.g. acetylcholine by exocytosis.
5. Acetylcholine diffuses across the synaptic cleft and bind to receptors on the postsynaptic neuron, that is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a chemical neurotransmitter from the axon terminal of a presynaptic neuron.
6. This causes sodium ion channels in the postsynaptic neuron to open, and sodium ions diffuse in.
7. Excitatory (excited neurons) postsynaptic potentials are created, and if these generator potentials are sufficient then the postsynaptic terminal reaches threshold potential and there is propagation.
Explanation: The nervous system is made up of billions of specialized cells called neurons, it is crucial to have an efficient communication between neurons for normal functioning of the central and peripheral nervous systems. The presynaptic action potential refers to an action potential of neuron before synapse. The above is the sequence of event during the transmission of information across the synaptic cleft
Explanation:
it is a unsaturated fatty acid.
Foods rich in unsaturated fatty acids, such as olive oil (oleic acid, an eighteen-carbon unsaturated fatty acid, is a major component) tend to be liquid at room temperature.
