**Core Concept**
Pain and temperature sensation in the human body are carried by the spinothalamic tract, a type of sensory pathway. This pathway is responsible for transmitting nociceptive and thermoreceptive information from the body to the brain. The spinothalamic tract is a critical component of the anterolateral system, which conveys pain and temperature sensations.

**Why the Correct Answer is Right**
The spinothalamic tract is composed of two main types of neurons: the primary afferent neurons, which are nociceptors or thermoreceptors, and the secondary afferent neurons, which are the axons of the spinothalamic tract. These neurons transmit signals from the body to the thalamus, where the information is processed and relayed to the primary somatosensory cortex for conscious perception. The spinothalamic tract is responsible for transmitting both the location and intensity of pain and temperature sensations.

**Why Each Wrong Option is Incorrect**
* **Option A:** The dorsal column-medial lemniscus pathway is responsible for transmitting vibration, proprioception, and fine touch sensations, not pain and temperature.
* **Option B:** The trigeminal nerve primarily conveys sensory information from the face, including pain, temperature, and touch, but it is not responsible for transmitting pain and temperature from the rest of the body.
* **Option D:** The lateral spinothalamic tract is involved in the transmission of crude touch and pressure, not pain and temperature.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the spinothalamic tract is a bilateral pathway, meaning that pain and temperature sensations can be perceived on both sides of the body even if the stimulus is unilateral. This is due to the crossing of the spinothalamic tract neurons at the level of the spinal cord.

**Correct Answer:** C.
