Put red information into a clean bulleted form:
Certain principles of muscle function help us to understand bone-muscle
relationships.
First, skeletal muscle contracts only if it is stimulated by the nervous system.
Second, skeletal muscles usually produce movements by pulling on bones
across joints.
The bones serve as levers and the joints serve as fulcrums. Third, muscles
usually lie next to the bones they move.
muscles usually act in groups.

Dissection Kit
Tray
Chicken Wing
Gloves
Procedure Step 1
• Carefully extend the wing to find out how many major
parts it has.
• Include a photo of the external structure.
Label: upper arm, elbow, lower arm, and hand.
(wing tip).
hand
Bad Picture! This is a
picture of his hand, not the chicken
wing.
Good Labels!!
Procedure Step 2
Use scissors to cut the skin as shown .
Try not to cut through the muscles located beneath the
skin
Procedure Step 3
The end of
the
muscle is
at the tip
of the
bone.
Procedure Step 4
The left top
muscle
was the
bicep and
the lower
right
muscle is
the tricep.
Procedure Step 5
The bottom
left is the
extensor
digitorum.
The right side
is called
abductor
pollicus
longorus.
Procedure Step 6
• The fat is the
white
gelatinous
Procedure step 7
The white
line within
the muscle
are the
tendons
and the
stretched
white in the
elbow is
also one.
Procedure step 8
• The inside elbow
has a ligament to it.
Procedure step 9
The top
white layer
above the
bone is
cartilage.
Procedure step 10
• Once you have identified the following
parts: skin, muscle, tendon, ligament,
cartilage and bone, call your instructor
over for a group oral quiz.
Procedure step 11
Clean UP!!!
• Throw away all chicken wing parts into
the designated garbage can.
• Put dissection tools into beaker of
soapy water. Stack tray next to beaker.
Wash your hands thoroughly with
soap and water.
Questions: (hint
hint!write them in your
notebook!!!)
1.
What function is performed by ligaments?the Ligaments have the job of flexing and
What is the function of a tendon? the function of the ligaments are to flex the muscle and reflex it, The function
for the tendons are the separate pieces of the ligament that are in direct contact with the muscles.
2.
What is more proximal, the insertion or the origin for the attachment of the muscles in the chicken wing?
the origin is more proximal to the body.
3. What tissue is referred to when one speaks of the “meat” of the chicken?
they are talking about the muscle in general.
4.
Name the two main types of movement that occur when a wing is raised and lowered in flight?
the two types of movement are called flex and reflex.
5. What bone in the wing is connected to the chicken’s body at the shoulder?it is the humerus, which is attached to
the humeral head then the scapula.
6.
Name the two bones found in the forearm of the wing? The radius and the ulna.
7.
What type of joint connects the wing to the body? it’s a ball and socket joint.
8.
9.
What type of joint moves the wing at the elbow? it’s a fixed joint where it only moves in two directions.
The muscle you observed is classified as what type of muscle tissue? the bone we observed is classified as
skeletal muscle.
