Study Notes

Nervous System: General Info

The mammalian nervous system consists of two main subdivisions: Central Nervous System (CNS) and Peripheral Nervous System (PNS).

Central Nervous System (CNS)

The CNS is composed of the brain and spinal cord.
The CNS receives and processes information, stores memories, generates thoughts and emotions, and initiates responses.
The brain is responsible for processing information and controlling responses.
The spinal cord conducts signals to and from the brain and controls reflex activity.

Peripheral Nervous System (PNS)

The PNS is composed of all neural bodies outside of the CNS, including receptors, nerves, and ganglia.
The PNS connects the CNS to the limbs and organs of the animal.
The PNS can be further divided into two main divisions: Sensory Afferent Division and Motor Efferent Division.

Sensory Afferent Division

The sensory neurons bring information to the CNS from receptors in peripheral tissues and organs.
The sensory afferent division can be further subdivided into Visceral Sensory Division and Somatic Sensory Division.
The Visceral Sensory Division collects information about internal organs via visceral receptors and sensory neurons.
The Somatic Sensory Division collects information about position, touch, pressure, pain, and temperature via somatic receptors and sensory neurons.

Motor Efferent Division

The motor neurons carry commands from the CNS to the peripheral tissues and organs.
The motor efferent division can be further subdivided into Visceral Motor Division and Somatic Motor Division.
The Visceral Motor Division provides autonomic regulations of cardiac muscle, smooth muscle, glands, and adipose tissue, which are all under involuntary control.
The Somatic Motor Division controls skeletal muscle contractions, which are under voluntary control.
The Visceral Motor Division can be further subdivided into Sympathetic Division and Parasympathetic Division.
The Sympathetic Division is known as the "fight or flight" autonomic response.
The Parasympathetic Division is known as the "rest and digest" autonomic response.

Neuro Exam

A hands-off neuro exam involves observing the patient's level of consciousness, content of consciousness, posture, and gait.
A hands-on neuro exam involves observing the patient's cranial nerves, postural reaction, spinal nerves, and nociception.
The overall purpose of any neuro exam is to localize the problem.
