Explanation:
The nerves leading to the central nervous system are called afferent nerves. Afferent nerves are responsible for carrying sensory information from the periphery of the body to the central nervous system (CNS), which includes the brain and spinal cord. These nerves transmit signals related to touch, temperature, pain, pressure, and other sensory stimuli from the sensory organs and receptors to the CNS.

Types of Nerves in the Peripheral Nervous System:
In the peripheral nervous system (PNS), there are two main types of nerves: afferent and efferent nerves.

1. Afferent Nerves:
- Afferent nerves are also known as sensory nerves.
- They carry sensory information from the peripheral tissues and sensory organs to the CNS.
- Afferent nerves transmit signals related to touch, pain, temperature, pressure, and other sensory stimuli.
- These nerves provide the CNS with information about the external environment and the internal state of the body.
- Afferent nerves are responsible for our ability to feel and perceive sensations.

2. Efferent Nerves:
- Efferent nerves are also known as motor nerves.
- They carry motor commands from the CNS to the peripheral tissues, muscles, and glands.
- Efferent nerves control our voluntary and involuntary movements.
- These nerves transmit signals that initiate muscle contraction and glandular secretion.
- Efferent nerves are responsible for the execution of motor responses in the body.

Summary:
In summary, the nerves leading to the central nervous system are called afferent nerves. These nerves carry sensory information from the periphery of the body to the CNS. Afferent nerves play a crucial role in our ability to feel and perceive sensations. On the other hand, efferent nerves carry motor commands from the CNS to the peripheral tissues, muscles, and glands, allowing us to initiate voluntary and involuntary movements.
