I love interaction and scientific dicussion. Never be afraid to ask me questions. I may not have the answer, but I'll be damned if I haven't learned how to do a good, quick Google Scholar search to find out.
In addition I like to look at non-science related cute animal pictures, art and funny comics too :)
Hope you enjoy my blog but please, feel free to leave suggestions for improvement!
Peripheral Nervous System
The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.
- Somatic Nervous System
The somatic nervous system consists of peripheral nerve fibers that send sensory information to the central nervous system AND motor nerve fibers that project to skeletal muscle.
The cell body is located in either the brain or spinal cord and projects directly to a skeletal muscle.
- Autonomic Nervous System
The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. The autonomic nervous system controls smooth muscle of the viscera (internal organs) and glands.
This picture shows the general organization of the autonomic nervous system. The preganglionic neuron is located in either the brain or the spinal cord. This preganglionic neuron projects to an autonomic ganglion. The postganglionic neuron then projects to the target organ. Notice that the somatic nervous system has only one neuron between the central nervous system and the target organ while the autonomic nervous system uses two neurons.
The enteric nervous system is a third division of the autonomic nervous system that you do not hear much about. The enteric nervous system is a meshwork of nerve fibers that innervate the viscera (gastrointestinal tract, pancreas, gall bladder).
TED-Ed: Under the hood: The chemistry of cars
View full lesson: http://ed.ted.com/lessons/under-the-h…
There are over one billion cars in the world right now, getting people from point A to point B. But cars aren’t just a mode of transportation; they also teach an excellent lesson in chemistry. Cynthia Chubbuck navigates the intricate chemistry performed in our car engines that keep them from getting too hot or too cold.

A The patient presented with difficulty breathing and sepsis and was admitted to the intensive care unit and put on a respirator. It took two weeks of manual evacuation attempts and enemas, before the blockage was finally dislodged.
Mozart, Beethoven or even Shakespeare — pregnant mothers have been known to expose their babies to many forms of auditory stimulation. But according to researchers at the University of Florida, all a baby really needs is the music of mom’s voice.

Dear everyone, this is huge
I’m not much of a signal booster, but I feel like this is something everyone should be talking about
Not just because of the shortage of blood donations in the US (and the need for blood) but the social implications.
EQUALITY. BIOLOGY. EQUALITY. BIOLOGY.
The scene takes place in the residence of my anatomy professor, the table is adorned with fine china and the smell of freshly brewed tea.
Beside the table sit my lab mates and academic inspiration, wide smiles and warm welcomes.
We chat about surgeries, dissections, clinical experiences, surfers ear and of course, teas.
After our tea and dainty snacks, we were treated to the stop motion film of my professors daughter. Nothing like army figurines and Barbie dolls to put you on an emotional roller coaster.
To make matters better, I received a thank you card from the students I ta-ed this Summer.
I may not have much to my name but I have the privilege of kind, intelligent and supportive company.
My thanks to all the people in my life, past or present, in person or by pixels
How diamonds and lasers can recreate Jupiter’s core
Understanding what the insides of the biggest planets in the universe has been largely wrapped up in theories. Now scientists at Lawrence Livermore National Lab have recreated these conditions with the help of diamonds and the world’s largest laser:
Though diamond is the least compressible material known, the researchers were able to compress it to an unprecedented density, greater than lead at ambient conditions.
The hope is to understand how these planets evolve over time by being able to reproduce their immense pressures. You can read more about it here.
