Chapter 29 Flashcards
Governs organs such as the heart, stomach, and intestines
Autonomic nervous system
Prepares the body for resting and digesting food
Parasympathetic branch
Insulates axons and allows them to send impulses quickly
Myelin sheath
The control center for a neuron
Cell body
The brain and spinal cord
Central nervous system (CNS)
Takes impulses to the cell body
Dendrite
Releases neurotransmitters to transmit impulses between neurons
Axon
Produces the “ fight or flight” response
Sympathetic branch
Consists of the nerves outside the brain and spinal cord
Peripheral nervous system
Carries impulses away from the cell body
Synaptic knob
T/F the decision making function of the nervous system takes place in the CNS
True
T/F
The autonomic nervous system is part of the CNS
False - PNS
T/F
Motor neurons carry information from the periphery to the CNS
False- sensory neurons
T/F
Another term for sensory neurons is afferent nerves
True
T/F
an anox without in Mylan sheath does not conduct a nerve impulse as quickly as myelinated anox
True
T/F
Pierre matter is the area and the meninges that contains cerebrospinal fluid (CSF)
False- subarachnoid space
T/F
The cervical enlargement of the spinal cord contains motor neurons that control muscles of the legs
False- lumbar enlargement
T/F
The cerebrum is the largest part of the brain
True
T/F
The midbrain includes the Thalamus in the hypothalamus.
False-dyaesthalm
T/F
Oculomotor nerves carry visual information to the brain for interpretation.
False- optic
T/F
The trigeminal nerves innervate muscles of facial expression.
False-facial nerves
T/F
The somatic nervous system consists of nerves that connect the CNS to the skin and skeletal muscle.
True
T/F
Ganglia are collections of neuron cell bodies in the CNS.
False- outside the CNS
T/F
The efferent nerves transmit impulses from the CNS the peripheral nervous system.
True
T/F
The trochlear nerves are tested by asking a patient to smell various substances.
