Hemorrhage: Bleeding or the abnormal flow of blood. A hemorrhage may be "external" and visible on the outside of the body or "internal," where there is no sign of bleeding outside the body. ... The term "hemorrhagic" comes from the Greek "haima," blood + rhegnumai," to break forth; a free and forceful escape of blood.
Explanation:
Internal bleeding occurs when blood leaks out through a damaged blood vessel or organ. External bleeding happens when blood exits through a break in the skin. Blood loss from bleeding tissue can also be apparent when blood exits through a natural opening in the body, such as the: mouth.
Answer: Third-order neurons
Explanation:
Third-order neurons in the thalamus, brainstem, and midbrain project to the central nervous system, which allows pain perception and interpretation.
Also, the limbic and reticular tracts are activated by third-order neurons, resulting in arousal and emotional responses to pain.
When stimulated, nociceptors (first-order neurons) in the skin, muscles, joints, arteries, and viscera transmit pain impulses to the spinal cord.
Second-order neurons in the dorsal horn of the spinal cord transmit the pain impulse to higher brain areas via spinal pathways.
The thalamus is the primary relay station for pain impulses.
