Task 1

The stimulus is touch sensation in the skin fingers. X Gramattical Correction: The stimulus of touch sensation is in the skin figures. Explanation: The stimulus of touch sensation is present in all parts of the body not only skin fingers.

Touch sensation is converted to action potentials by sensory receptors, which summate and form graded potentials = TRANSMISSION v. Gramattical Correction: Touch Sensation in converted into action potential by sensory receptors, which form into graded potentials= Transmission.

These graded potentials travel along efferent neuron as an impulse toward the ventral horn of the spinal cord = TRANSDUCTION. X Explanation: It is a process in which DNA transfers from one bacterium to another by a virus.

The impulse arrives at the lumbosacral segments of the spinal cord and causes the release of the inhibitory neurotransmitter. This excites the second order neuron v

The second order neuron for touch decussates in the spinal cord of the peripheral nervous system and is part of the spinothalamic tract. v

The second order neuron sends impulses to the basal ganglia of the cerebellum, as the basal ganglia is a sensory relay station. v

The basal ganglion relays impulses onwards to the ipsilateral primary motor cortex which is involved with sensations from body parts = PERCEPTION. X

Grammatical Correction: The basal ganglion relays impulses onwards to the ipsilateral primary motor cortex which is involved in producing sensations from body parts.

Explanation: Perception is the process of understanding the environment or circumstances by interpreting sensory information. Impulses arrive from the fingers of the opposite side of the body and topographic representation of information is maintained from the body surface to the cortex.v

It is the cortex that processes the information to generate an awareness of the location, intensity and quality of the touch sensation. The meaning of the stimulus is worked out by the primary cortex = SENSATIONv

Grammatical Correction: Cortex processes the information to generate an awareness of the location, intensity and quality of the touch sensation. The meaning of the stimulus is worked out by the primary cortex.

The size of the cortex given over to receiving information is in proportion with two-point discrimination of the body parts, with sensitive body areas having smaller areas of cortex for processing. v

The statements that wrong needs proper explanation. Student has not properly explained Transduction and other concepts. Background and detail of information is very ...
