Thalamus- The thalamus is the uppermost part of the brainstem. It directs information to the sensory cortex and provides feedback to the cerebellum and medulla. 3. Medulla- The foundation of the brainstem. It manages heartbeat and breathing. 4. Reticular formation- The nerve region travelling through the brainstem and thalamus. The network is responsible for governing arousal. 5. Cerebellum- The area located directly behind the brainstem. It processes sensory input‚ organizes movement‚ helps sustain

muscles cause the fibers’ calcium-binding capacity to decrease‚ which then limits muscle contraction‚ which causes muscle fatigue. (Mullick) During muscle fatigue‚ feedback of nerve impulses from the fatigued muscles interrupts on a part of the reticular formation and causes a hang-up of voluntary effort. (Amussen) It is important to understand that muscle fatigue results from metabolic reasons and not structural changes in your muscle. Peripheral muscle fatigue involves the motor units‚ such as motor

the dermis provides tensile strength and elasticity to the skin through its dermal fibres (collagen‚ reticular‚ and elastic fibres) that are embedded in an extrafibrillar matrix [72‚ 73]. The dermis is approximately 15 to 40 times thicker than the epidermis and can be further divided into a superficial part adjacent to the epidermis‚ the papillary dermis‚ and a deep thicker part‚ the reticular dermis. The papillary dermis interdigitates with the epidermis and is mostly composed of loosely arranged

Chapter 20- List the functions of the lymphatic vessels. The function of the lymphatic vessels‚ or lymphatic’s‚ is an elaborate system of drainage vessels that collect the excess protein-containing interstitial fluid and return it to the bloodstream. Describe the structure and distribution of lymphatic vessels. The lymphatic collecting vessels have the same three tunics as veins‚ but the collecting vessels are thinner walled‚ have more internal valves‚ and anastomose more. The lymphatic

Information travels along the axon in the form of an electric charge called the action potential. terminal buttons Tiny bulblike structures at the end of the axon‚ which contain neurotransmitters
