Document Summary
Three meninges cover the brain: dura mater hard mother thick like leather outer layer, arachnoid spider (greek) space between dura and pia, pia mater gentle mother inside brain. Most choroid plexus is found within the ventricular system, in the brain. Spaces within the brain that contain csf are called ventricles. The ventricular system is a series of ventricles and canals that move csf within the brain and. Your ventricular system contains about 150ml of csf. You produce 500ml of csf/day transport in out to the subarachnoid space. The cutaneous sensation is perceived by touch receptors, also known as mechanoreceptors. Proprioception the sense of limb position. Kinesthesis the sense of limb movement. Receptors are not concentrated in one location, like the retina or cochlea. Peripheral nerves terminate in either the spinal cord (spinal nerves) or brain stem (cranial nerves) Most sensory receptors of the somatosensory system are mechanoreceptors.
