The Spinal Cord

The central nervous system controls all voluntary movement (e.g. walking) and involuntary movements, such as breathing.  The brain is like a central computer or center of command of the body. 

The brain control thoughts, perceptions, emotions, interpret the external environment, and control body movement among many other things. It interprets information from our sensory organs like eyes (sight), ears (sound), nose (smell), tongue (taste), skin (touch), and our internal organs.

The spinal cord is the nerve pathway that allows communication between the brain and body.  When the spinal cord is injured, the exchange of information between the brain and other parts of the body is disrupted.

The spinal cord consists of repeated structures called segments.  These segments are divided into cervical, thoracic, lumbar, and sacral groups.


El cordón espinal:

El sistema nervioso central controla todos los movimientos voluntarios (por ejemplo, caminar) y movimientos involuntarios, como respirar. El cerebro es como una computadora central o centro de mando del cuerpo.

El cerebro controla pensamientos, percepciones, emociones, interpreta el ambiente externo y controla el movimiento corporal entre muchas otras cosas. Interpreta información de nuestros órganos sensoriales como ojos (vista), orejas (sonido), nariz (olor), lengua (sabor), piel (tacto) y nuestros órganos internos.

El cordón espinal es la ruta nerviosa que permite la comunicación entre el cerebro y el cuerpo. Cuando el cordón espinal sufre una herida, el intercambio de información entre el cerebro y otras partes del cuerpo se ve interrumpido.

El cordón espinal consiste en estructuras repetidas llamadas segmentos. Estos segmentos se dividen en grupos cervicales, torácicos, lumbares y sacrales.
