Aracnoides: it is one of the three meninges that protect the central nervous system, bone marrow and brain. It lies between the other two meninges.

Axón: it is a lump of neurons by the emerging signals, or nerve impulses to be transmitted to other cells.

Bulb rachidian: A pyramid is inverted and is placed right above the spinal cord. is responsible for the nerve impulses that control the actions automatic as breathing.

Brain Crust: outer layer of the brain, known as gray matter. It consists of millions of neurons.

Cell: basic unit in the composition of living things. It can function on an individual basis in unicellular organisms.

Cerebelo: part of the brain located in the area below it. It is responsible for all impulses associated with the movement, coordination and balance of the musculoskeletal system.

Corps callosum: joining the two cerebral hemispheres and transmit signals from one to another.

Dendritas: nerve endings are acting as receivers of signals from other neurons.

Diencefalo: lies between the two hemispheres and is crossed by many of the nerve endings of the cerebral cortex.

Duramadre: it is one of the three meninges that protect the central nervous system, consisting of the brain and spinal cord. It is the outer layer and harder.

Epitalamo: it is a part of diencéfalo. It locates the pineal gland. Situated at the top of the thalamus.

Frontal Lobe: it is one of the four parties that often divide the brain. Its main functions are those related to the language.

Hemisferios brain: each of the two halves is not symmetrical, in which the brain is divided.

Hypothalamic: gland, which secretes various classes of hormones. Está situada en el diencéfalo. It lies in the diencéfalo.

Parietal lobe: one of the four lobes of the brain which is divided. It is the area where the sensations are processed perceived as cold or heat.

Occipital Lobe: it is one of the four parties which divides the brain. It relates to the visual function.

Marrow oblong: A pyramid is inverted and is placed right above the spinal cord. It is responsible for the nerve impulses that control the actions automatic as breathing. Also called rachidian bulb.

Neurona: is a type of cell capable of receiving and sending signals in the form of nerve impulses. The signals are sent from the axon of one neuron to the dendrites of another.

Neurotransmitters: chemicals that carry signals to other neurons around. We adhere to the dendrites or neural receptors and produce a neuron in the excitation or inhibition.

Synapses: union established between two neurons for the transmission of information. It is necessary to bear in mind that the neurons are not physically together.

Tálamo: part of diencéfalo in which it receives all the information captured by the senses.

Temporal lobe: one of the four parties that is often split the brain and that usually relates to memory or ability to retain knowledge.
