One thing you did have at that stage was a reasonably complete peripheral nervous system. The nerve cell bodies in and near your central nervous system sent out axons into the rest of your body, including your extremities. Many of these axons did not persist; they failed to find innervation ...
Incidentally, the spinal cord ofPatagotitanwas something like 120 feet long, and the longest DC-ML primary sensory neurons ran all the way from tail-tip to brainstem before they synapsed, making them among thelongest cells in the history of life. ...
Step 1- p.341 Motor neuron receives an impulse Motor Unit or Neuromuscular Junction 1. Neuron 2. Sarcolemma (or motor end plate) 3. Vesicle 4. Synapse 5. Mitochondria Step 2 – p.341 Motor neuron releases the neurotransmitter acetylcholine into the gap between the neuron and the muscle Step...
While researchers have uncovered many details regarding the roles these SCs play, little is known about how they interact with the muscle's connecting site for motor neuron signalling; the neuromuscular junction (NMJ). The NMJ is composed of a coral-like arrangement of acetylcholine receptors (...

To get back to Luke’s question, there are loads of interesting things that could be dissected in a sauropod, but since the remit here is Matt Wedel x titanosaur, there’s only one possible answer: the lung/air sac system and its diverticula. For several reasons: ...
