Muscle Flashcards
what motor units are recruited at lower forces
small motor units
what motor units are recruited at higher forces
large motor units
where do neurons originate
spinal column
where do neurons terminate
neuromuscular junction
what are the characteristics of small motor units
smaller membrane surface area
action potential easier to generate
what are the characteristics of large motor units
more membrane surface area
action potential harder to generate
what is the structure of a unipolar neuron
dendrites and a single axon extending as a fused process
what are the functions of unipolar neurons
sensory receptors
what is the structure of a bipolar neuron
one dendrite and one axon extending from the cell body
what is the function of the bipolar neuron
make up of special sensory organs such as the retina
what is the structure of the multipolar neuron
multiple dendrites and a single axon extending from the cell body
what is the function of the multipolar neuron
make up the majority of the central nervous system
characteristics of smooth muscle
single nuclei
not striated
autonomic control
characteristics of cardiac muscle
visible striation
single nuclei
autonomic control
allows heart to pump blood
characteristics of skeletal muscle
highly organised striation
multiple nuclei
voluntary control
