Chapter 16 part 2 Somatic sensory pathways

Front

What carries impulses from the brain/spinal cord to the thalamus?

Back

2nd order neuron.

Front

What carries impulses from the thalamus to the primary somatosensory area of the cortex?

Back

3rd order neuron.

Front

Where are joint kinesthetic receptors located?

Back

Within or around articular capsules.

Front

Which somatic sensory pathway transmits sensory impulses for tactile, thermal, and pain from the face, nasal and oral cavities, and teeth?

Back

Trigeminothalamic pathway.

Front

Which neurons always decussate?

Back

2nd order neuron.

Front

What is the role of 1st order neurons in somatic sensory pathways?

Back

They carry sensory impulses from sensory receptors to the spinal cord.

Front

What is the function of 2nd order neurons in sensory pathways?

Back

They transmit impulses from the spinal cord or brainstem to the thalamus.

Front

What is the primary function of 3rd order neurons?

Back

They carry impulses from the thalamus to the cerebral cortex.

Front

What type of receptors are responsible for detecting joint position and movement?

Back

Joint kinesthetic receptors.

Front

What is the difference between the posterior column medial lemniscus pathway and the anterior lateral (spinothalamic) pathway?

Back

The posterior column medial lemniscus pathway transmits fine touch and proprioception, while the anterior lateral pathway transmits pain and temperature sensations.
