**Core Concept**
Conus Medullaris syndrome is a neurological disorder caused by injury to the conus medullaris, the lowermost part of the spinal cord. It is characterized by a specific set of clinical features that result from the disruption of nerve fibers and motor neurons in this region.

**Why the Correct Answer is Right**
Conus Medullaris syndrome typically presents with a combination of clinical features, including:
- Sacral sensory loss: Patients often experience numbness, tingling, or loss of sensation in the sacral dermatomes (S4-S5).
- Urinary retention: The conus medullaris contains nerve fibers that control the bladder and urethral sphincter, leading to urinary retention in affected individuals.
- Lower motor neuron signs: These include muscle weakness, atrophy, and decreased reflexes in the lower extremities.
- Autonomic dysfunction: Patients may experience orthostatic hypotension, impotence, and other autonomic disturbances due to the involvement of autonomic nerve fibers in the conus medullaris.

**Clinical Pearl / High-Yield Fact**
Conus Medullaris syndrome is often associated with traumatic injuries to the lower spine, such as falls from a height or motor vehicle accidents. It is essential to recognize this condition early, as prompt treatment can improve outcomes and prevent long-term complications.
