Touch: 1st order is _________, it decussates at the ___________ neuron and end up in a ___________ 3rd order neuron.

Discriminative touch includes the following subcategories, with following receptors:

Which receptors are superficial?
Are they sensitive to light energy?

Deep receptors include

Which receptors are fast adapting?

Which receptors are slow adapting?

Make a table of the speed of adaptation, receptive field size, submodality, and functional application of the four main somatosensory receptors.

Muscle spindles comprises ______, ______, and ________ axons.

Ia afferent is (fast/slow) adapting while II afferent is (Fast/slow) adapting.

Muscle spindles sit (parallel/ perpendicular) to the muscle fibers. They are good at sensing _____.

Ib afferent axon is found in the ________. It senses changes in ________.

Priprioception fibers are _______ fibers. Touch receptors are ________ fibers.

(proprioception/touch) axons are extremely rapidly conducting.

Touch neuron are less myelinated, but still _______.

T/F: 1st degree neurons for touch and proprioception travel in the dorsal column in the CONTRALATERAL side of stimulus.

Cell body of 1st degree sensory neurons lie in the _________.

The 1st order sensory neurons synapse with the second order neurons in the ______ (UE) or _________(LE) in the medulla.

The pathway in which 2nd order neuron travels is called the _________. It synapses with the 3rd order neuron in the _______.

In the dorsal column of the spinal cord, the more distal the body region is, the more (lateral/medial) the 1st order axon travels.

The touch and proprioception sensory system is also called the _______.

The fibers that cross the center of the body are called _________.

Where in the thalamus does the DCML 2nd and 3rd order neurons synapse with each other?

After leaving the VPL, the 3rd order axon enters the _______ and travels along the _____ into its respective area in the __________.

Which lamina does the 3rd order axon terminate?

Order of BA from central sulcus to postcentral sulcus.

BA 1 integrates ______ inputs to achieve ________.

BA 1 sends projection fibers to BA2, which integrates ________ information to differentiate ________.

BA2 also sends output projections to BA5, which also gets commisural input from other fields, to integrate ______ activities.

It also has body-body synthesis, which is referred to as _______ reference.

BA7 combines self image with visual inputs to give us ________, which is also called ______.
