Anesthesia Anatomy
Anesthesia Anatomy
Neurons
Neurons are the longest cells in the body that are responsible for conducting nerve impulses or signals including pain and other exterior senses.
Dendrites
Dendrites are a part of neurons in which allow each neuron to receive incoming messages.
Epineuriums
Peripheral Nerves
Tissues that are affected by anesthesia include the Epineurium which occupies the entire nerve fibers and loosely holds it to the other connective tissues.
Peripheral nerves are consisted of neurons and are the part of the nervous system located outside of the brain and spinal cord. Within anesthesia neurons, dendrites, and axons conduct pain sensations in which the peripheral as well as spinal nerves are dulled to decrease the feeling of pain during operations.
Axons
Overview and tissues
Axons also known as nerve fibers are also located inside of neurons and can have multiple lengths. Axons are responsible for conducting outgoing messages.
Within anesthesiology, an understanding of the body or anatomy is needed. This aspect is required in order to keep anesthesiologist aware of the body parts that should be affected. Anatomy is heavily used during regional anesthesia since only specific parts need treatment. The main areas that anesthesia affects are connective tissues and peripheral/spinal nerves inside of the injected area. Connective tissues are formed by dorsal and ventral roots under the first levels of skin. And connective tissues of spinal nerves are grouped into epineurium, perineurium, and endoneurium categories.
Endoneuriums
Endoneuriums are the fine connective tissues inside of fascicles that surrounds each nerve fiber or axon.
Perineuriums
Perineuriums surround groups of axons that bundle together to form nerve fascicles.
