muscles are made up of many which are made up of many
A large mass of muscles is made up of .
Fibers contain two types of protein, and .
Actin is a filament, and myosin is a filament.
Muscles are attached to with .
Muscles are made up of , which are made up of , which are made up of .
Proteins when stimulated and cause the muscle to .
muscles are named after their appearance. They work in with a muscle, for example the biceps and triceps.
Each muscle cell is either or not, and of muscle cells determines .
Normally muscle is neither completely nor completely .
The basic element of the motor unit system consists of , cells, and the .
The basic element of the motor system is the .
A motor neuron, or an motor neuron, can innervate many muscle fibers.
The neuromuscular junction is the connection between the and the .
Motor units with fibers cells tend to control more muscle movements than movements with fiber cells.
Alpha motor neurons are large neurons that innervate muscle.
(cell bodies) are in the ventral of the and , axons extend through the ventral and .
A neuromuscular junction is the meeting of an and a
The junction works like a between nerves, with the transmitter .
The , (BA & ) controls higher order control of motor functioning (planning, organization, and logic)
The frontal (BA 8) are responsible for movement.
Broca's Area (BA 44 & 45) is responsible for generating used for .
The primary motor area (BA ) is to the central sulcus.
The primary motor area is directly involved in the production of . It demonstrates organization, where each hemisphere demonstrates control.
The is the beginning of the . The neurons are arranged in that control a small group of muscles.
The pyramidal system controls movement, but the extrapyramidal system controls and movement.
Mysthenia gravis involves motor problems with the . Lambert-Eaton involves issues with the .
The columns are then arranged in that control of muscles.
The pyramidal system is named for the large pyramidal () cells. It is responsible for of volitional movement. It is made up of two major tracts, and .
Betz cells are located primarily within the ()
The motor system is a neuron chain that links the cerebral cortex to the skeletal muscles via one of the two
The upper motor neuron is entirely within the and the lower motor neuron goes from the to the muscle.
The include voluntary pathways for movement of all speech and swallowing muscles, except respiration.
It begins at the and terminates at the of cranial nerves in the .
Exceptions to the bilateral innervation include the (intermediate) and the and face (unilateral).
Upper motor neurons are also known as neurons. LMN are also known as motor neurons, and make up the .
LMN receive input from many in addition to the UMN.
