Achtlyn (Actin) and Maya-Sing (Myosin) would love if you could draw their portraits to hang up in the Sarcolemma!
Draw the two as detailed as possible to show their unique differences
For Actin --> distinguishing factors should be the heads
For Myosin --> actin 'pearls,' troponin, and tropomyosin
What is the difference between the orbicularis oculi and the orbicularis oris?
Can you point them out?
The orbicularis oculi closes the eyes and the orbicularis oris puckers the lips
Our names hint to how many origins we have
One of us flexes the forearm while the other extends it
Who are we and which one performs which action?
Biceps brachii (flexion of the arm) and Triceps brachii (extension of the arm)
There are two of us who perform the same action.
When we contract, we cause flection of the vertebral column, causing the abdomen to compress
Who are we?
Rectus abdominus and transverse abdominus
What are the four muscles of the quadriceps?
Rectus femoris
Vastus lateralis, intermedius, and medialis
Insertion and Origin live in the same muscle and are very much in love, but they live so far away!
On the biceps brachii , can you draw where they live?
PS: you get an extra 20 points for showing me the movement AND telling me the type of muscle movement involved
In a quick schematic, Origin would be more proximal and Insertion more distal
The movement would be holding your arm out and bringing your forearm closer to you
This movement is flexion
What are these two muscles?
What connects them?
Frontalis and Occipitalis
they are connected by an aponeurosis
Our names both contain brachi- , and we perform the same actions, but we have different endings
Who are we?
Can you point us out on a model?
brachialis and brachioradialis
what muscles make up the mnemonic phrase "I love Spine?"
Which is most lateral and which is more medial?
Iliocostalis (more lateral)
Longissimus
Spinalis (more medial)
What are the 3 muscles of the hamstrings and the movements they create?
Biceps femoris, semimembranosus, and semitendinosis
All 3 have the same action of flexing the leg and extending the thigh
We're Sarco-Meary's sisters. People often confuse the both of us, even though we're different
One of us is thin and the other is thick. We help Sarco-Meary contract when she has to. One of us gives very strong power strokes.
Who are we? And which one of us does power strokes?
Achtlyn (Actin) and Maya-Sing (Myosin)
Maya-Sing(Myosin) is responsible for power strokes
We are two twins with the same name. One of us is larger than the other, but the smallest of us lives above the bigger one.
One of us pulls up on the upper lip, while the other one of us pulls the lips into a smile -- who are we and which of us does which action?
Can you point us out to Keila ?
The muscles are zygomaticus major and zygomaticus minor
The major is what pulls the lips into a smile while the minor pulls up on the upper lip
If this muscle originates from the distal end of the humerus and inserts at the phalanges, what kind of movement would you see?
What kind of muscle(s) would satisfy this description?
(note: one answer is fine, but two answers (if correct) might be better....)
flexion of the hand and digits
Flexor digitorum superficialis and/or flexor digitorum profundus
We have similar jobs that help in respiration, but we each do different things.
One of us helps in inspiration, while the other helps in expiration -- who are we, and which once performs which action?
External intercostals (inspiration) and internal intercostals (expiration)
Can you identify the 4 muscles being pointed to?
Tensor fascia latae
Gracilis
aDductor magnus
Piriformus
Hi, my name is Sarco-Meary(Sarcomere)! Can you please draw my two brothers? They look just like me!
Can you also draw the NeuroMusklair Train Junction? Its our favorite place to hang out !
(label ALL points of interest on BOTH drawings)
There should be TWO sarcomeres
Should include: the Z lines, M lines, thin and thick filaments, the zone of overlap, the A band, I band, and the H zone
NMJ: should include synapse, vesicles, Ach, Ach receptors, and end plate
PS: her brothers names are Sarco-Mario and Sarco-Larry
A) What am I pointing to?
B) What muscle is normally over this?
C) What happens if the right portion of muscle A contracts ?
A) Stenoclioidmastoid
B) The Platysma
C) If the right stenoclioidmastoid contracts, the head rotates to the right
What are we pointing at?
Can you identify the movements made by these muscles?
Note: there are 2 movements for each muscle, both must be correct for the win
flexor carpi radialis and flexor carpi ulnaris
they felt the hand, but radialis also aBducts it while the ulnaris aDducts it
I am one of the larger muscles on the body
My 3 parts span from the base of the skull to clavicle (superior), to the scapula to the upper vertebral column (middle), and to the scapula through down halfway to the back (inferior)
My movements allow adduction, elevation, and also depression of the scapula, while also being able to extend the head
Who am I ?
trapezius
Point out the following
1) Sartorious
2) Gluteus medius
3) aDductor longus
My name is Maya Figbrel and I have a VERY big family. We live in tight bundles inside one of the Fass-Ikeyl districts.
There are MANY Fass-Ikeyl districts and my family is spread out throughout them.
Can you please draw the bundle of my family district, the other bundle districts, and the whole city that we live in?
(aka: draw a complete schematic/cross section of a muscle, and label EVERYTHING)
The cross section should include: the myofibril, muscle fiber, endonysium, facile, perimysium, and the epimysium
Can you show me where the masseter is?
What kind(s) of movements do you expect to see from this muscle?
PS: you get 20 extra points if you can can name more than 1 movement
elevates, protracts, and retracts the mandible
Can you point out the following muscles ?
1) aBductor pollicis longus
2) extensor carpi radialis brevis
3) extensor digitorum
4) extensor pollicis brevis
Given the movements, what muscles would act in this way?
1) depress the scapula
2) rotation of the scapula (specify which rotation)
3) aDducts the arm
4) aBducts the arm
Possible answers....
1) pectoralis minor, trapezius
2) rhomboid major/minor (inferior rotation), serrates anterior (superior rotation)
3)pectorals major, latissimus dorsi, infraspinatus, teres major
4) deltoid, supraspinatus
Name 3 muscles that cause plantar flexion and point them out on a model
Possible muscles:
Gastrocnemius, soleus, tibialis posterior, fibularis longus, fibularis brevis, flexor digitorum longus, or flexor hallucis longus
