Document Summary
In the brain, we integrate sensory input with appropriate motor output. Neurons: specialized for carrying electrical signals, synapses, specialized structure areas that allow neurons to connect with another neuron to carry out a functional responses, targets effector cells. Glia: astroctyes, brain and spinal cord, maintain chemical environment. Cns: neurons found in nuclei, axons travel in tracts, e. g. corticospinal tract, myelinated by oligodendrocytes. Vertebral column: spinal cord is protected by the vertebrae, vertebral column is made up of approximately 26 vertebrae. Spinal cord: each spinal nerve always exits from the intervertebral foramen below its vertebral coutnerpart, e. g. Lumbar puncture (spinal tap: site to obtain cerebrospinal fluid, devoid of spinal cord, best to be inserted between l3-l4 or between l4-l5, can inject agents (e. g. antibiotics) Spinal cord spaces: three layers of meninges cover and protect the spinal cord, create natural spaced between the layers.
