Nervous System Flashcards
Central Nervous system is in charge of
Integration and control
The CNS consists of
The cerebral cortex and cerebellum
Brain stem
Spinal cord
Peripheral Nervous system is in charge of communication between
The communication between the CNS and the rest of the body
PNS consists of
12 pairs of cranial nerves
31 pairs of spinal nerves
Sensory neurons are efferent or afferent?
Afferent- info comes in.
Somatic and Visceral
Motor neurons are efferent or afferent?
Efferent- information going out
Somatic and Visceral
Somatic nervous system is voluntary or involuntary?
Voluntary
CNS to skeletal muscles
Autonomic neurons are
Involuntary/visceral and go from
CNS to cardiac/smooth muscles and glands
Medulla oblongata and the ANS, Medulla oblongata helps regulate
Breathing heart rate and blood pressure
Medulla oblongata and the ANS, Medulla oblongata helps reflex
Coughing vomiting and swallowing
Sympathetic neurons consist of a preganglionic neuron that is
Short
Sympathetic neurons consist of a postganglionic neuron that is
Long
Parasympathetic neurons consist of a preganglionic neuron that is
Long
Parasympathetic neurons consist of a postganglionic neuron that is
Short
Sympathetic trunk/ chain refers to which ganglia
Paravertebral ganglia
Pre ganglion of cell bodies sit where
They sit in the lateral horn of spinal cord T1-L2
Visceral efferents exit via ventral roots with
The somatic efferents
What is the neuron that releases ACh known as
Cholinergic neuron
Neurons that release NE or E are known as
Adrenergic neurons
Parasympathetic effects on the body are
Short lived and highly localised control
Sympathetic effects on the body are (THINK ADRENALINE)
Long lasting and body wide effects where adrenaline gets released from adrenal medulla into whole systemic circulation
