Sensory Pathways

These flashcards cover key terms and concepts related to sensory pathways, including major pathways and their functions.

Somatic sensory pathways

Carry sensory information from skin and muscles to the CNS.

Spinothalamic pathway

Responsible for conscious sensation of pain, temperature, and crude touch.

1st order neurons

Neurons that synapse with 2nd order neurons in the posterior horn.

Decussate

The process by which neurons cross from one side of the CNS to the other.

Posterior column pathway

Carries sensations of fine touch, pressure, vibration, and proprioception.

Dorsal column medial lemniscus (DCML) pathway

Ascends on the same side to the medulla before decussating.

Primary somatosensory cortex

The final destination of the sensory pathways for processing sensory information.

Spinocerebellar pathway

Delivers proprioceptive information from muscles, tendons, and joints to the cerebellum.

Proprioception

The body's ability to sense its position and movement.

Conscious awareness of sensations

Refers to whether we are aware of sensory signals such as touch, pain, or pressure.
