1.Write the part of the brain that preforms each of the functions shown below.

Damm [24]

The parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

<h3>What is a brain?</h3>

A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.

In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

All chemical synapses exhibit the same general sequence of events during the transmission of information across the synaptic cle

Ne4ueva [31]

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
