It's behind the brain stem and connected to the brain stem. And then the last part, but not the least part of the brain, is this big part in the back. Under the pons, and the part that actuallyĬonnects to the spinal cord, is called the medulla, or medulla, or sometimes people use a longer name of medulla oblongata. Just below the mid brain we call the pons, P-O-N-S, for pons. The very top part of the brain stem that connects to the cerebrum, is called the mid brain, mid brain. And then the brain stem itself is divided into three smaller parts. To the spinal cord that they've cut off down Let me write that out, brain stem, which is all of this part right here that connects the cerebrum So first let me just draw an outline around this part right here, and this is the part that hooks onto the spinal cord down here. The cerebral hemispheres, and then the part on the bottom, which is smaller, we divide into two other parts. This stuff on the top, is the cerebrum or one of Left cerebral hemisphere, but we're looking at The middle part of the brain, so it's like we've cutĭown the brain this way, and separated the left and Now on this picture over here, we're actually looking at Cerebral hemispheres, like half a sphere. You can only see the cerebrum and you see that it's divided into a left and a right half, and we call those halves the cerebral, or cerebral hemispheres. Now if we look down from the top, like in this drawing here, you can't see the parts underneath. Cerebrum, which is theīiggest part of the brain and the part on top. All of this part on the top, that has several different colors here, is called the cerebrum. Here we're looking at theīrain from the left side. And I'll just mention some of the big ones for this kind of introduction talk. Now the brain is divided intoĪ bunch of different parts. That's this long thin tube-like structure that goes down the spine.
And the spinal cord which is in the spine. Made up mostly of the brain which is in the head. Central and peripheral, and both of those are themselves divided into two main parts. The first is called theĬentral nervous system.

Look up somatic in Wiktionary, the free dictionary.In this video I'm going to introduce the structure of the nervous system and the nervous system is divided into two main structural parts. Soma is the whole axial portion of an animal, including the head, neck, trunk, and tail. Thus far, the popular usage of this term has not fully realized this meaning, and a mind-body dualism still often occurs in disciplines describing themselves as somatic. The usage of somatic as put forth by Thomas Hanna implies a truly integrated mind/body/spirit nature of humans. According to the originator of this usage of the term, "somatic awareness allows a person to glean wisdom from within". In the philosophy of education, certain ideas that have to do with the body and the mind have been called somatics. For example, a somatic mutation cannot be transmitted to descendants in animals. In genetics, somatic can refer to a cell or tissue that resides outside the germline (see somatic cell). Additionally, somatic muscles are basically those of the musculo-skeletal system. In anatomy, somatic can refer to the part of the nervous system that controls voluntary movement and sensation and judges relative effort and weight, called proprioception. In neurobiology, somatic can be an adjective referring to the soma, the part of the neuron containing the cell nucleus. It has different meanings in various disciplines. The word comes from the Greek word Σωματικóς ( Somatikòs), meaning "of the body". The term somatic refers to the body, as distinct from some other entity, such as the mind.
