8.0 Nervous System Questions - Review & Structure Flashcards
In a reflex, the structure that monitors the environment is called the:
Sensory Receptor
The function of a sensory receptor is to:
Send messages about changes in the environment.
In a reflex, the structure that causes muscle contractions or secretion from glands is called the:
Effector
A neuron that carries a message from a sensory receptor to the brain or spinal cord is called a:
Sensory (Afferent) neuron
A neuron that carries a message away from the brain or spinal cord is called a:
Motor (Efferent) neuron

Spinal cavity
Sensory functions involve ______________ of the external and internal environment of the body.
Monitoring
Motor functions involve _______________ of skeletal muscles or secretions by glands.
Movement
What system PNS or CNS is responsible for sensory and motor functions?
PNS
(peripheral nervous system)
The process of putting information together from various areas of the body and making decisions to change something in the body is called:
Integration
What system PNS or CNS is responsible for integrative functions?
CNS
(Central nervous system)
What nervous system division is responsible for controlling skeletal muscles?
Somatic Nervous System
What nervous system division is responsible for controlling smooth muscles, cardiac muscles and glands.
Autonomic Nervous System
Effectors in the PNS (peripheral nervous system) are:
Skeletal Muscles
Effectors in the ANS (autonomic nervous system) are:
Smooth muscle, cardiac muscle & some glands
Nerve messages traveling from the receptors to the CNS are said to be:
Sensory (afferent)
Nerve messages from the CNS to the effectors are said to be:
Motor (efferent)
