Answer 1

a) posterior funiculus medial lemniscal pathway - sensory input of touch, proprioception and vibration

(The medial muscle in its spinal pathway (DCML) is a sensory pathway of the central nervous system. This is the traditional sense of touch, vibration, pressure, two-point discrimination, and proprioception (position) of the skin and bones.

Also note that in the posterior column - medial shape, and consists of two parts. The dorsal (posterior) column, which extends from the spinal cord, and the spinal cord, which extends to the vertebral column of the medial cortex, continues from there. From first to DCML it projects into the cortex from the path to the cortex from the somatosensory gyrus. )

b) anterolateral pathway- sensory input for crude touch, pressure, pain , temprature

(Anterolateral system is the somatosensory system teaches nociception, thermal sensations of physical origin and non-discriminatory contact. However, an ordinary and innocent freedom in the matter of small nociceptive nerve endings transduces, of diameter p, finely myelinated, unmyelinated, or to flood the somatic efferent fibers. These fibers are peripheral to the pseudounipolar small cell process at the back of the root (of the body) and triplet nodes (face).)

c) spinocerebellar pathway- innervates axial skeletal muscles

Information from the proprioceptive muscle of the plot, and that can convert the king muscle, which governs exuberant, and the receptors of the spinal cord of the lower joint to L1 in the Clarke nerve, C8 L4. Ipsilaterally upward along the dorsal spinocerebellar tract. With the inferior leaves are posterior to the cerebellum it is out of the treaty

d) corticobulbar tract- innervates cranial motor nuclei 5,7,9 and 12

The motor of the lower nucleus of the corticobulbar tract of the skull innervates bilaterally nuclear (which is under the eyes of the facial muscles innervates) and the genioglossus muscle is innervated by the contralateral cortex, but the task. And so it will form them speaking with a connection from the bilateral innervation trapping a little stronger than the grains contralaterally used ipsilaterally. Since in the course of one of the nerves of the skull, a nucleus innervates the corticobulbar 5, 7, 11, and 12. And also to the regions and contributes to the corticobulbar process in the nucleus of the oculomotor of the motor 10, and indeed undecided .

e) lateral corticospinal tract- sensory input for coordination of movements and proprioception

Damage to body parts and other defects cause loss, depending on whether or lower pyramidal decussatio (caudal). It will not cause damage to the body in the event of fire due to contralateral motor deficits. In fact, if they are on the right and left sides of the body affected by an injury to the brain, the cortex of the pre gyrus. Decussatio will damage pears with ipsilateral motor deficits. For example, spinal damage on the left side of the chest at the level of the left corticospinal tract may be motor defective.

F)anterior corticospinal tract- innervates limb muscles For skilled movements

The anterior corticospinal tract (ventral corticospinal tract is called the "speech bundle, Turck's lateral corticospinal tract," the direct pyramidal tract, or mumps in the muscle bundle) is a small group of fibers that connect the cerebral cortex that descends to the spinal cord. Going down the paths of the motor neurons of the brain above the previous psychiatrist handled depending on the meanings with which the reason forces immediate production and the lower motor neurons of movement. Usually, the small tract of the anterior flanks interacts with the body, which is the most important tract.
