2,2,2
Glycolysis takes place where?
Cytoplasm
The _____ nerve is NOT responsible for eye movement
Optic
Acetylcholine is a compound throughout the nervous system that functions as a ________
Neurotransmitter
The _________ postganglionic fibres does NOT use acetylcholine
Acetylcholine
Sensory input Is apart of the _______ nervous system
Afferent
The ____ nervous system is the brain, spinal cord, vertebrae and blood barrier
central
The _______ nervous system is the spinal and cranial nerves that carry messages from the body to the brain (afferent sensory) and the brain to the body (efferent)
peripheral
The peripheral nervous system is divided into the 1. Sensory (______) division and the 2. motor (_______) division
Afferent, efferent
There are ______ types of motor (efferent) divisions in the PNS
[motor=efferent=ME]
TWO
The two types of the motor divisions in the PNS are
- Sensory afferent and
2. motor efferent
The somatic motor (efferent) commands ______ response
SEV - voluntary to walk to sev
Voluntary
______ muscle is an example of the somatic (efferent) motor system
Skeletal
The _______ motor (efferent) commands _________ response
VEI - I involuntary feel vague
Involuntary
The visceral (efferent) is known as the
Autonomic nervous system ANS
Two functional divisions in ANS efferents:
Sympathetic and parasympathetic
The ANS consists of efferent motor neurons that
- innovate ______ and ______ muscle and ______
- Operates _______ control
Smooth and cardiac
Involuntary control
The _____ commands smooth muscle: dial ate airways, cardiac muscle: heart rate increase, also releases glucose from storage
ANS
The autonomic and somatic nervous systems are part of the motor (_______) divisions of the PNS
efferent
The ANS and SNS differ in
- Effectors (target organs and tissues)
- _______ pathways (and their neurotransmitters)
- Target organ _______ to neurotransmitters
Efferent
Responses
The somatic nervous systems effector is the ______ muscles
Skeletal
The ANS effector is _________ muscle, ______ muscle and ______
Cardiac, smooth and glands
The ______ efferent pathway is a thick, heavily myelinated somatic motor fibre that makes up each pathway from the CNS to the muscle
SNS
The _____ efferent pathway is a pre-ganglionic neuron that has a thin, lightly myelinated pre-ganglionic axon
ANS
The ______ neuron in autonomic ganglion has an un myelinated postganglionic axon that extends to the effector organ
ganglionic
In the SNS ALL SOMATIC NEURONS release what?
Acetylcholine (ACh)
In the ANS _____ganglionic fibres release ACh
Autonomic nervous syste
In the ANS ________ fibres release norepinephrine or ACh at effectors
postganglionic
“Rest and digest” is what system
Parasympathetic
Think- digest paracytes
What system Promotes maintenance activities and conserves body energy with decrease in blood pressure and heart rate and respiratory
Parasympathetic
Parasympathetic = pupils ________ and lenses are accommodated for ____ vision
Constricted
Close
“Fight or Flight” is what system
Sympathetic
Thinks - sympathetic for the fighting, flying bird
Increased heart rate, blood flow shunted to skeletal muscles and heart, bronchioles dilated and liver releasing glucose describes the _____ system
Sympathetic
The _____________ systems fibres originate at the brain and sacral spinal cord
Parasympathetic
Think- paralysed because the brain
The ______ systems fibres originate in the thoracolumbar region of the spinal cord
Sympathetic
“Short preganglionic and long post ganglionic fibres” describes what system
Sympathetic
