This is a biology question regarding nerve impulses.
Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1.

- which of the following does not describe the somatic nervous system? A. motor neurons that innervate glands, cardiac and skeletal muscle B. a system of motor neurons that innervate all muscle cells c. voluntary nervous system d. general sensory for skin and joints.arrow_forwardEmergency room doctors often shine a light into the eyes of patients with head injuries to test their pupillary reflex. The structure that relays the information between the optic nerve and the motor neuron, and the division of the nervous system that the structure is part of , respectively are: Select one: a. an interneuron and the peripheral nervous system b. the occipital lobe and the peripheral nervous system c. the occipital lobe and the central nervous system d. an interneuron and the central nervous systemarrow_forwardMany neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?arrow_forward
- Which of the following statements about the functional divisions of the nervous system is false?a. Somatic sensory neurons carry signals from a range of sources like skeletal muscles, the skin, and special sensory organs.b. Visceral sensory neurons carry signals from organs such as the heart and kidneys to the spinal cord and brain.c. Somatic motor neurons regulate involuntary secretions from glands and the contraction of smooth and cardiac muscles.d. The autonomic nervous system is a key regulator of homeostasisin the body.arrow_forwardThe extrinsic (extraocular) eye muscles allow you to direct your gaze toward particular objects, while the intrinsic muscles of the eye adjust the shape of the lens and the size of the pupil. These two sets of muscles are controlled by different components of the nervous system. Use logic to answer the following two questions: Group of answer choices Which division of the nervous system controls the extraocular eye muscles? (somatic "voluntary" nervous system/ autonomic "Involuntary" nervous system) Which division of the nervous system controls intrinsic muscles that adjust the pupil and lens? (somatic "voluntary" nervous system/ autonomic "Involuntary" nervous system)arrow_forwardThe reflex arc is the fastest way the body has to move a body part from danger or away from the source of pain. Have you ever noticed your own reflex response? Did you notice that you felt the pain after you yanked your hand away from the source of pain? Which is the sequence of structures involved in a reflex response? a. motor neurons → effectors → brain → sensory neurons → interneurons b. effectors → sensory neurons → brain → motor neurons c. sensory neurons → interneurons → motor neurons → effectors d. sensory neurons → motor neurons → interneurons → effectorsarrow_forward
