Final Exam: CV, NS, and SS Flashcards
Functional level of the nervous system that detects changes in the environment
Sensory
Functional level of the nervous system that is decision-making
Integrated
Functional level of the nervous system that evokes a response (muscle or gland)
Motor
What two parts is the Central Nervous System divided into?
Brain and spinal cord
What does the Peripheral Nervous System consist of?
Everything other than brain and spinal cord
The peripheral nervous system has two sub-systems. What are they and what is their importance?
Afferent nervous system: transmits information into the CNS.
Efferent nervous system: transmits information out of the CNS.
The Nervous System is divided into two ways in which the parts of it are controlled. What are they?
Autonomic Nervous System and Somatic Nervous System
Which of the two controlling parts of the nervous system is the motor system that controls glands, cardiac muscle, and smooth muscle (involuntary)?
Autonomic Nervous System
The Autonomic Nervous System is made of two sub-divisions. What are they?
Sympathetic Division: adapts the body for activity (blood pressures heart rate, blood glucose, blood flow).
Parasympathetic Division: calming effect on body function (resting and digesting).
Which of the two controlling parts of the nervous system controls the skeletal muscles (under voluntary control)?
Somatic Nervous System
Reflex Arc: what part is located in the skin or sense organs that detect a stimulus and create an impulse?
Receptors
Reflex Arc: which part conducts nerve impulses towards the central nervous system (brain and spinal cord), and carries messages from a receptor to the spinal cord?
Sensory Neurons
Reflex Arc: what part is in the central nervous system (brain and spinal cord), connects sensory neurons to motor neurons, and carries messages from a sensory neuron in the spinal cord to a motor neuron?
Interneurons
Reflex Arc: what part conducts nerve impulses from the central nervous system (brain and spinal cord) to an effector, and carries messages from the spinal cord to an effector?
Motor neurons
Reflex Arc: what part responds to the impulses by contracting (if the effector is a muscle fiber) or secreting enzymes or hormones (if the effector is a gland)?
Effectors
