Behavioral Science 1.2 Flashcards
Sensory(afferent) neurons
Transmit sensory information to the spinal cord and brain
Motor (efferent) Neurons
Transmit motor information from the brain and spinal cord to muscles and glands
Inter neurons
Middle man - in between other neurons
Reflex arc
Causes immediate response to pain/danger rather than transmitting the signal to the brain and relaying response. Occurs in interneurons
The nervous system is subdivided into the_____ & _______ Nervous systems
Central and peripheral
Central nervous system
Consists of the brain and spinal cord - transmit signals through the body
Peripheral nervous system
Connects the body sensory and control to the central nervous system
The central nervous system consists of the_______&_______
Brain and spinal cord
The peripheral nervous system consists of the________&_________
Somatic and autonomic nervous system
Autonomic nervous system
(automatic)- regulates heartbeat respiration digestion and glandular secretions. All subconscious activities
Somatic nervous system
Extends throughout many tissues of the body and controls muscle movement and sensory information. Signals travel along afferent fibers and afferent fibers.
The autonomic nervous system is divided into______&________
Parasympathetic and sympathetic
Parasympathetic nervous system
Primarily serves to conserve energy. Elicits actions are associated with sleep like reducing heart rate constricting pupils contracts the bladder and stimulates flow of saliva.
Sympathetic nervous system
Activated by stress and elicits a fight or flight response. Causes bodily functions like increasing heart rate redistribution of blood to muscles increasing blood glucose decreasing digestion and dilating the eyes.
