Study Notes
Nervous System Overview
- Specialized network of cells responsible for transmitting electrochemical signals is called neurons.
- The nervous system can be divided into voluntary (somatic) pathways and involuntary (autonomic) pathways based on responses.
Control Systems
- The endocrine system provides control over many different functions performed by cells, tissues, and organs.
Nervous System Divisions
- The autonomic nervous system's sympathetic division is responsible for the 'fight or flight' response.
- The central nervous system (CNS) comprises the brain and spinal cord.
Main Functions
- The central nervous system's main function is processing and integrating sensory information while coordinating responses.
- Two essential vital functions of the nervous system include maintaining homeostasis and facilitating communication between body parts.
Nervous System Structure
- The two main divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS).
- Somatic nervous system controls voluntary movements by affecting skeletal muscles.
Autonomic Nervous System
- The main function of the parasympathetic division of the autonomic nervous system is to promote rest and digest functions in the body.
Cell Types
- Neuroglial cells support and protect neurons, whereas neurons are the primary cells that transmit signals.
Nervous Pathways
- Nervous pathways can be divided into two parts based on information direction: afferent pathways (sensory) and efferent pathways (motor).
- Effectors regulated by the autonomic nervous system include smooth muscles, cardiac muscles, and glands.
Neuron Types
- To remember the difference between sensory neurons and motor neurons: sensory neurons convey information to the brain from sensory receptors, while motor neurons transmit responses from the brain to effectors.
