What do muscle do? |
Breathing, Pumping Blood, Balance, Vision and Digesting Food
|
There are 5
|
|
|
What are the 3 types of muscle?
|
Skeletal, Visceral (smooth), Cardiac
|
|
|
|
What does the skeletal muscle do?
|
Attaches to bone! Moves parts to the skeleton! It is striated (visible line)! Voluntary! Controlled consciously!
|
|
|
|
What does the Visceral do? |
No striations, involuntary (not always controlled, found in intestines and the walls of blood vessels and internal organs.
|
|
|
|
What does the Cardiac do? |
Involentary, some striations/bands, found in the walls of the heart |
|
|
|
What many percent does the skeletal muscle weight of one's body?(If they fall within the normal range) |
40% |
|
|
|
Muscles contain? |
nerve tissue (electrical supply), nervous blood vessels, fibres, and a individual fibre |
|
|
|
List some reasons why muscles are named after |
Shape; trapezius, size; maximous/minimus, action; flexor/extersor, points of attachment; sternoleidomastoid |
|
|
|
How many muslces are there in the human body? |
Over 600 |
|
|
|
What is a tendon? Origin? Insertion? |
Muscles attach to bone via a fibrous band of connective tissue which is a tendon. They are attached at one end by a fixed point know as the origin, and the other end of a movable part/joint which is an insertion |
|
|
|
Are the origin and insertion are never on the same bone? |
Yes |
|
|
|
What is the direct result if an antagonistic relationship? |
Our abiltily to move smoothly at varying speed that exists between (groups) opposing muscles. |
|
|
|
What is a primeover? |
When a muscle or group is contracted the group on the opposite side if the bone (antagonist) is needed in order to resist the full extent of contraction |
|
|
|
Example of antagonist? |
when th ewuads are contracted the hamstrings (the antagonist)act to prevent or approve the wuad from making our foot over the head. |
|
|
|
What will happen if a muscle is deprived of exercise? |
The muscle will decrease in size. To the minimum required level (ATROPHY) |
|
|
|
If the muscle is worked hard.....? |
It will increase in size, HYPERTROPHY |
|
|
|
Name the physsiology of the Muscle Tissue |
Irritabiliyu, Extensibily, Elasticity, and contracctility |
|
|
|
Whats irritanility? |
The ability of the living tissue (muscle)to respond to stimuli(sight, smell, taste, hearing) |
|
|
|
Whats contracctility? |
When stimulated by nerve implulses, the muscles become shorter and thicker |
|
|
|
Whats Extensibility? |
The antagonist realtionship between opposing nmuscles mrans that when one muscle contracts the other must lengthen |
|
|
|
Whats Elasticity? |
After a muscle has been contracted it has the ability toi return to uts original length and width |
|
|
|
Name the muscles of the cheeks |
Masseter, risorous, zygomatic major, buccinator |
|
|
|
Whats the diffreence between origin and insertion? |
Origin doesn't move and insertion does |
|
|
|
Name the parts of a skeletal muscle |
Belly, tendon, aponeurosis tendon, peristeum and bone |
|
|
|
Name the types of muscles and mentally draw them |
Fusiform, Unipennate, bipennate, multipennate, bicipital, triangular |
|
|
|
Why is our facial muscles the most unique? |
Cause |
|
|
|
Name the biggest to smallest of a muscle |
Muscle, bundle, fibre, myofibril , myofilament and then scromere |
|
|
|
Who created the sliding filament theory? |
H.E. Huxley |
|
|
|
What are the main substances in the sliding filament theory? How long are they? |
Acetycholine-ACH Adenosine Tri-Phosphate- ATP Calcium-Ca2+ Adenosine Di-Phosphate- ADP |
|
|
|
What is the fast twitch? |
Develops muscle tension rapidly Produces large amounts of power for a short time Has a hjigh anarobeic metabolism small amount of mitochondria and poor blood supply greatest potential for enlargement (hypertrophy) large numbers of motor neurons fast condition of impulses to the muscle Activity during change of pace and stop and go activities such as basketball and ice hockey as well as activities that require rapid, powerful movements like sprinting and weight lifting |
|
|
|
What is short twitch? |
Develops tension slowly as compared to fast twitch. Cannot produce large amounts of power but is more resistant to fatigue. Responsible for postural adjustments. Has a high potential for aerobicv metabolism (high capacity for fatty acid metabolism). Is utilized during prolonged activity that require a steady rate of aerobic energy transfer. Is alway reqcruites first. |
|
|
|
What are the main function of the lower body? |
locomotion, balance and power |
|
|
|
What are the 4 major muscles of the quads? |
Sartorius, Vastus Lateralis, Rectus Fernoralis, Vastus Medialis |
|
|
|
What's the Myiad of Expressions?
|
The Myriad of Expressions portray attitude, mood, and consumption of food
|
|
|
|
What does the muscle of the neck provide?
|
Provides stability and mobility
|
|
|
|
List the rounds of the cycle in the sliding filament theory
|
ACH is released from the motor burton to the motor end plate, ATP and calcium ions are released by the sarcoplasmic reticulum and sent through the muscle via the T tubules, An ATP ase (myosine) causes a phosphate to split from the ATP to create energy for contraction, ATP = ADP + P + energy, Actin and Myosin myofilament overlap the sacromere shortcut, An ACH are inhibits the release ACH to the muscle, ADP and Calcium are transformed into the SR. A+P is resybthesiszed

What's Kyomgraph
|

|
|
|

|
The appartus that is used to measure muscle activity
|

|
|
What is phase 1?
|
The brief period between the stimulus and the initial contraction called the latent period lasts for .01 seconds
|

What is phase 1?
|
The brief period between the stimulus and the initial contraction called the latent period lasts for .01 seconds
|
|
|
|
What's phase 2?
|
Called the contraction phase lass for about minimum of .04 seconds
|
|
|
|
What's phase 3?
|
The tied phase (if the contraction stops) called the relation phase lass for about .05 seconds. Lasts for .05 seconds, before he next contraction of the same muscle can take place of a recovery period in which oxygen supplies are replenished and calcium is returned to "storage" in the muscle
