Study Notes
The Mammalian Nervous System
- The mammalian nervous system has 2 major subdivisions: Central Nervous System (CNS) and Peripheral Nervous System (PNS)
Central Nervous System (CNS)
- Comprises the brain and spinal cord
- Protected by armor-like skull and vertebrae
Peripheral Nervous System (PNS)
- Consists of receptors, nerves, and ganglia
- Connects the CNS to limbs and organs
Sensory Neurons
- Receives and processes sensory information
- Initiates responses, stores memories, and generates thoughts and emotions
- Brings information to the CNS from receptors in peripheral tissues and organs
Motor Neurons
- Carries motor commands from the CNS to peripheral tissues and systems
- Conducts signals to and from the brain, controlling reflex activities
- Controls skeletal muscle contractions (voluntary control)
Neurological Examination
- Main objective: to understand the patient's problem and locate the lesion
- Hands-off examination: assesses level of consciousness, content of consciousness, posture, and gait
- Hands-on examination: assesses cranial nerves, postural reactions, spinal nerves, and nociception (sensitivity to painful stimuli)
Key Terms
- Afferent: relates to sensory neurons
- Efferent: relates to motor neurons
