Let's solve this step by step based on the diagram of a
skeletal muscle and the provided terms.
Given Terms:
- blood vessels
- bone
- endomysium
- epimysium
- muscle fascicle
- muscle fiber
- perimysium
- tendon
Now, let’s identify each numbered part in the diagram:
---
1.
This is the structure at the end of the muscle that attaches to the
bone. It's a tough connective tissue that connects muscle to bone.
✔ Answer: Tendon
---
2.
This is the
bone to which the tendon attaches. The muscle pulls on this bone during contraction.
✔ Answer: Bone
---
3.
This is the
outermost layer surrounding the entire muscle. It's a thick connective tissue sheath.
✔ Answer: Epimysium
---
4.
This is a
bundle of muscle fibers, also known as a
fascicle. It's surrounded by connective tissue.
✔ Answer: Muscle fascicle
---
5.
These are the
individual muscle cells (muscle fibers) within a fascicle. They are grouped together in a fascicle.
✔ Answer: Muscle fiber
---
6.
This is the
connective tissue surrounding each individual muscle fiber. It's the innermost layer.
✔ Answer: Endomysium
---
7.
This is the
connective tissue surrounding a group of muscle fibers (a fascicle). It's thicker than endomysium but thinner than epimysium.
✔ Answer: Perimysium
---
8.
This is the
network of blood vessels that supply oxygen and nutrients to the muscle fibers.
✔ Answer: Blood vessels
---
Final Answers:
1.
Tendon
2.
Bone
3.
Epimysium
4.
Muscle fascicle
5.
Muscle fiber
6.
Endomysium
7.
Perimysium
8.
Blood vessels
---
Summary of Connective Tissue Layers (from outside to inside):
-
Epimysium → surrounds the entire muscle
-
Perimysium → surrounds each fascicle
-
Endomysium → surrounds each individual muscle fiber
And the
tendon connects the muscle to the
bone, while
blood vessels supply the muscle tissue.
✔ All parts labeled correctly!
