Chapter 1.1 (page 4) Flashcards
These are the nervous system’s 2 principle divisions.
Central Nervous System
Peripheral Nervous System
This consists of the brain and spinal cord. This is the integrating and command center of the nervous system. This interprets incoming sensory information and dictates responses based on past experience, reflexes and current conditions.
Central Nervous System
This division of the nervous system consists mainly of the nerves that extend from the brain and spinal cord. This consists of sensory and motor divisions.
Peripheral Nervous System
What are the 3 overlapping functions of the nervous system?
Sensory Input
Integration
Motor Output
The CNS is the integrating and __________ of the nervous system.
Command Center
The sensory division has two parts; sensory ________ relays information to the CNS from skin, joints and skeletal muscles.
Somatic
__________ relays information to the CNS from the visceral tissues.
Sensory Visceral
The motor division has two parts; the _____________ sends information from the CNS to skeletal muscle; the ______________ sends information from the CNS to organs.
Somatic motor division
Autonomic nervous system (ANS)
The ANS has two parts: _________ and ____________ divisions.
**Sympathetic
Parasympathetic **
These the changes occurring both inside and outside the body that are monitored by millions of sensory receptors.
Sensory Stimuli
The gathered information by the sensory receptors is called ________ .
Sensory Input
It is the process wherein the nervous system processes and interprets the sensory input and
makes decisions about what should be done at each moment.
Integration
This is the activation of effector organs (muscle or gland tissue) as a response to stimuli.
Motor output
