Dissectible Me 5 minute anatomy

Fascia is classically described as a series of sheets of connective tissue wrapping the body and compartments within it. It holds us together and gives us shape. But what is fascia?

The embryonic period in humans is the first 8 weeks after fertilisation. What happens during the embryonic period and why is it different to the foetal period?

The anatomy of spinal nerves is rather neat, but can also be confusing. Let me talk about the dorsal and ventral roots, sensory and motor neurones, the spinal nerve and its posterior and anterior rami.

What anatomy would I include if I only had 5 minutes to talk about forearm? I think I'd group the muscles, movements and nerves together to better understand what movements would be affected by a nerve injury.

The autonomic nervous system innervates the sino-atrial node and controls the rate of contraction of the heart. What other effects do sympathetic and parasympathetic nerves have on the heart? I can think of two more.
