Anatomy terms unit 4
three ways muscle fibers produce ATP
1. creatine phosphate 2. anaerobic glycolysis 3. aerobic respiration
Aponeurosis is shaped like?
A sheet like
low stimulus frequency
Adequate relxation
What kind of tissue is fascia?
Areorlar CT
What is the innervation of scapula muscles?
Brachial plexus
What kind of CT is tendons?
DRCT
What three types of connective tissue?
DRCT,DICT,areolar
What type of tissue is tendons?
Dense regular CT
Where do we get oxygen from?
Diffusion from blood through hemoglobin into muscle fibers and release from myoglobin in sacroplasm
What innervation of facial expression
Facial nerve
What 2 ingredients are in a Anaerobic CR?
Glycolysis- 2 ATP and Pyruvic acid
high stimulation frequency
Inadequate relaxation
Infused tetanus
Inadequate time to reaax
isometric contraction
Muscle contracts but there is no movement, muscle stays the same length
Innervation
Nerve that tells muscle to do its stuff
What is the innervation of the lower limb?
Obturator nerve
Tendons have strength in?
One direction?
Sacrolemma
Plasma membrane
Myrofibrils
Proteins that allow muscle contraction
Tone
Small amount of motor units that don't produce movement
Terminal cisterns
Stores Calcium and is where bulk of Calcium is stored
contraction period
Time where sacromere is shortening
relaxtation period
Time where sacromere is sliding back to normal length
What is the innervation of muscles of the mastifcation?
Trigeminal nerve
transverse tubules
Tunnel that allows ions/electrical current to get to deep parts
Define twitch
a quick cycle of contraction and relaxation
creatine phosphate
acts as an energy reserve in muscle tissue
What is the innervation of upper limb?
brachial plexus
Sacroplasm
cytoplasm of a muscle cell
Recruitment
increase in the number of motor units activated
isotonic eccentric
muscle lengthens
Tendons attach what to what?
muscle to bone
isotonic contraction
muscles contract and shorten
unnaturally high stimulus frequency
no relaxation between stimuli
fused tetanus
no relaxation phase at all
anareobic respiration
requires no oxygen
aerobic respiration
requires oxygen
sacroplasmic reticulum
stores calcium
Endomysium
surrounds each muscle fiber
Epimysium
surrounds entire muscle
Perimysium
surrounds fascicles
Latent period
time between stimulus and contraction
