Sure! Here’s a quick overview of the nervous system:

### Components of the Nervous System:

1. **Central Nervous System (CNS)**:
- **Brain**: The control center for processing and coordinating sensory information, and regulating bodily functions.
- **Spinal Cord**: Connects the brain to the peripheral nervous system, transmitting messages to and from the brain.

2. **Peripheral Nervous System (PNS)**:
- **Somatic Nervous System**: Controls voluntary movements and transmits sensory information to the CNS.
- **Autonomic Nervous System**: Regulates involuntary functions (heart rate, digestion).
- **Sympathetic Nervous System**: Prepares the body for stress or emergency (fight or flight).
- **Parasympathetic Nervous System**: Restores the body to a state of calm (rest and digest).

### Functions of the Nervous System:
- **Sensory Input**: Receiving information from sensory receptors about the environment.
- **Integration**: Processing and interpreting sensory input and deciding on a response.
- **Motor Output**: Sending signals to muscles and glands to produce a response.

### Key Cells:
- **Neurons**: The basic units of the nervous system that transmit signals.
- **Glial Cells**: Support cells that aid in the maintenance and functionality of neurons.

### Disorders of the Nervous System:
- **Neurological Disorders**: Such as Alzheimer's, Parkinson's, multiple sclerosis, and epilepsy.
- **Injuries**: Such as spinal cord injuries or traumatic brain injuries.

### Quick Assessment:
1. **Reflex Testing**: Checking knee-jerk and other reflexes can assess neural pathways.
2. **Sensory Response**: Testing touch, pain, and temperature sensation in various body parts.
3. **Motor Function**: Evaluating strength, coordination, and balance.
