Trace the impulse, listing the steps in as much detail as possible,

Customer Question

Trace the impulse, listing the steps in as much detail as possible, from which your brain sends the message to the appropriate muscles to lift a glass of water to drink. What are the steps involved in the transmission of the neural impulse to the muscle fiber and then the steps involved in the sliding filament theory? Which muscles are pulling on which bones and what type of joints are involved in lifting a glass? (Part two) Finally, trace the path of the water from the mouth to the urethra, listing the path in as much detail as possible.

Part one:

Part two:

1. Macroscopic Neurology – trace impulse macroscopically through the nervous system from the brain to the muscle.

2. Microscopic Neurology – trace impulse as it passes through the neuron, neuron to neuron, and across the NMJ:

3. Sliding Filament Theory explanation.

4. Muscles, bones and joints utilized in lifting the glass – i.e. The long head of the biceps brachii muscle contracts, pulling on the humerus to cause flexion across the shoulder joint which is a ball and socket type of synovial joint and assists in reaching toward the glass of water.

5. Path of water from entry at the oral cavity to its exit at the external urethral orifice – and everything in between and in detail – i.e. oral cavity, pharynx, esophagus, stomach, small intestine, absorption into bloodstream, passage through the kidney and its nephrons in detail, renal pelvis, ureters, bladder storage, urethra, exit body at external urethral orifice
