Muscle excitation/contraction
This neurotransmitter is released at the skeletal muscle neuromuscular junction
what is Acetylcholine
This muscle assists in closing the eyelids
what is Obicularis Oculi
This is muscle atrophy
what is a decrease in the size of a muscle
This happens when (throughout the sarcomere) the thin filaments slide past the thick ones
what is shortening of the muscle
This muscle causes extension of the great toe
What is the Extensor Hallucis Longus
This enzyme breaks down acetylcholine in the synaptic cleft
what is Acetylcholinesterase (AChE)
This type of muscle is found in the walls of hollow organs (intestines) and moves substances through the organ.
what is smooth muscle
If this muscle is paralyzed the patient cannot breath on their own. (the most important muscle for respiration)
what is the diaphragm
This muscle extends the thumb
what is Extensor pollicis brevis
These are the three phases of a muscle twitch
what is Latent (lag), Contraction and Relaxation
The motor end plate is a specialized region of the sarcolemma that contains these receptors
what is Acetylcholine receptors
When referring to muscles, Brevis means this
what is short
This thick fibrous band of connective tissue is involved in the pathophysiology of carpal tunnel syndrome
what is the Flexor retinaculum
The iliopsoas allow for this movement
what is hip flexion
Multiple motor unit summation increases force by this mechanism
what is Recruitment (recruiting more motor units)
This type of contraction involves no change in muscle length
what is isometric
This is the word used Muscles that function together to produce movement
what is synergists
This bacteria causes Tetanus
what is Clostridium tetani
This muscle group is responsible for knee extension
Calcium reabsorption into the sarcoplasmic reticulum causes the muscle to do this
what is relax
This occurs in the muscle during isotonic, concentric contraction
what is muscle shortening (contraction, with same tension)
These are three muscles that assist in mastication
What is: Temporalis
Digastric
Masseter
Electrolyte loss, K+ accumulation and ADP/Pi accumulation cause this
what is muscle fatigue
These are the four main Abdominal muscle groups
Rectus abdominus
External/Internal obliques
Transverse abdominis
Partial relaxation between muscle contractions causes this type of muscle stimulation
what is Incomplete tetanus
