Upper motor neurons - Study guides, Class notes & Summaries

The upper motor neurons are axons that carry action potentials from the upper brain (cerebrum) to the brainstem or spinal cord A reflex is an automatic response to a stimulus produced by a reflex arc The lower motor neurons have cell bodies in the anterior horns of the spinal cord and in the brainstem These are all properties of reflexes except __________. A) reflex responses are very predictable. B) reflexes are responses to sensory inputs

LDA Neuro Questions & Answers, latest updates. 100% Accurate. 1) Describe two functions of the meninges. - a. Forms a "PAD" around the brain in the skull- almost like a balloon of fluid for the brain to sit in so no pressure is on the bottom of the brain i. It makes movement slower to create less of an impact- therefore protecting the brain from too fast of movement and gravity of the brain b. Carries cerebral-spinal fluid; carrying or being a vehicle in which blood vessels bring nutrie...
