Answer 4

Answer in detail. Choose the correct statements. a) the eustachian tube protects the eardrum from damage due to changes in atmospheric pressure b) synapse - this is a contact only between the end of the axon and the dendrite c) the work of the heart is regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system d) veins are called vessels through which venous blood flows e) the bodies of neurons form the gray matter of the cortex and nuclei in the white matter f) the lowest pressure in the circulatory system is in the capillaries

The correct statements are:

- a) the eustachian tube protects the eardrum from damage due to changes in atmospheric pressure. This is true because the eustachian tube connects the middle ear to the nasopharynx and helps to equalize the pressure on both sides of the eardrum. - c) the work of the heart is regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. This is true because the sympathetic division increases the heart rate and the force of contraction, while the parasympathetic division decreases them. - d) veins are called vessels through which venous blood flows. This is true because veins carry blood from the tissues to the heart, while arteries carry blood from the heart to the tissues. - e) the bodies of neurons form the gray matter of the cortex and nuclei in the white matter. This is true because the gray matter consists of neuronal cell bodies, dendrites, and unmyelinated axons, while the white matter consists of myelinated axons.

The incorrect statements are:

- b) synapse - this is a contact only between the end of the axon and the dendrite. This is false because synapses can also occur between the end of the axon and the cell body or the end of the axon and another axon. - f) the lowest pressure in the circulatory system is in the capillaries. This is false because the lowest pressure in the circulatory system is in the veins, especially the vena cava, which is the largest vein in the body. The pressure in the capillaries is higher than in the veins, but lower than in the arteries.
