Fungsi Rangka Manusia (Sistem Gerak)
Summary
TLDRIn this educational video, Weti Yuningsih introduces the topic of the human movement system for 11th-grade students. The discussion begins with the skeletal system, highlighting the difference between passive movement (skeletal system) and active movement (muscular system). She explains the two types of skeletons—exoskeletons in invertebrates and endoskeletons in vertebrates and humans. Additionally, the video covers the functions of the skeletal system, such as giving shape, protecting organs, supporting muscles, enabling movement, producing blood cells, and storing minerals. The video concludes with a promise of more content on the axial skeleton.
Takeaways
- 😊 Introduction to the topic of human movement system for 11th-grade material.
- 👣 The movement system in humans consists of two types: passive (skeletal system) and active (muscular system).
- 🦀 There are two types of skeletons: exoskeleton (external skeleton in invertebrates like grasshoppers, cockroaches, lobsters, and crabs) and endoskeleton (internal skeleton in vertebrates and humans).
- 👤 The skeletal system in humans gives shape and posture to the body.
- 🛡️ The skeleton protects soft organs like the heart, brain, lungs, and spinal cord.
- 💪 The skeleton provides a place for muscles (skeletal muscles) to attach, which are crucial for movement.
- 🏃 The skeleton supports movement by acting as a structure for muscles to work against.
- 🩸 Hematopoiesis, the formation of blood cells, occurs in the red bone marrow.
- ⚙️ The skeleton serves as a storage for minerals, especially calcium.
- 🔔 Next topic to be covered: the axial skeleton in the human skeletal system.
Q & A
What are the two types of movement systems in humans?
-The two types of movement systems in humans are passive movement (skeletal system) and active movement (muscular system).
What is the passive movement system in humans?
-The passive movement system in humans is the skeletal system, which provides structure and support to the body.
What is the active movement system in humans?
-The active movement system in humans is the muscular system, which enables movement by contracting and relaxing muscles.
What are the two types of skeletons mentioned in the script?
-The two types of skeletons are exoskeleton and endoskeleton.
What is an exoskeleton, and which organisms have it?
-An exoskeleton is a skeleton located outside the body, commonly found in invertebrates such as grasshoppers, cockroaches, lobsters, and crabs.
What is an endoskeleton, and which organisms have it?
-An endoskeleton is a skeleton covered by muscles and skin, found in vertebrates and humans.
What are the primary functions of the skeletal system in humans?
-The skeletal system provides body shape and posture, protects soft organs, serves as attachment points for skeletal muscles, facilitates movement, aids in hematopoiesis (blood cell formation), and stores minerals like calcium.
How does the skeletal system protect the body?
-The skeletal system protects the body by shielding vital soft organs such as the heart, brain, lungs, and spinal cord.
What is hematopoiesis, and where does it occur in the body?
-Hematopoiesis is the process of blood cell formation, which occurs in the red bone marrow found within the skeletal system.
What will be the next topic discussed in the video series according to the script?
-The next topic to be discussed in the video series is the axial skeleton in the human skeletal system.
Outlines
🧑🏫 Introduction to the Human Movement System
The video begins with a greeting by Weti Yuningsih, who introduces the topic for the day: the human movement system, a key part of the 11th-grade curriculum. The focus is on the movement system's two components: the passive movement system (skeletal system) and the active movement system (muscular system). She urges viewers to pay close attention as they explore these foundational concepts.
💀 Types of Skeletons: Exoskeleton vs Endoskeleton
The second part of the video introduces two types of skeletons. The exoskeleton, which is found outside the body, is typical of invertebrates like grasshoppers, cockroaches, lobsters, and crabs. In contrast, the endoskeleton is covered by muscles and skin, characteristic of vertebrates, including humans.
🏋️♂️ Functions of the Human Skeleton
The next section delves into the functions of the human skeletal system. The skeleton provides body structure and posture, protects soft organs such as the heart, brain, lungs, and spinal cord, serves as a point of attachment for skeletal muscles, supports movement, enables hematopoiesis (blood cell production in the red bone marrow), and stores minerals like calcium.
🎓 Conclusion and Teaser for Next Topic
The video wraps up the discussion on the human skeletal system, specifically its functions in movement. The presenter then previews the next lesson on the axial skeleton in the human body. Finally, she encourages viewers to like and subscribe to the channel for more educational content.

Hai Hai assalamualaikum warahmatullahi
wabarakatuh ketemu lagi dengan saya Weti
Yuningsih kali ini kita akan membahas
materi kelas 11 yaitu tentang sistem
gerak yang pertama kita bahas adalah
alat gerak dan fungsi rangka di smack
baik-baik ya sistem gerak pada manusia
itu terdiri dari dua macam yang pertama
adalah alat gerak pasif yaitu sistem
rangka yang kedua ada alat gerak aktif
yaitu sistem otot selanjutnya kita bahas
tentang macam Skeleton Skeleton ada dua
macam yang pertama ada
exoskeleton merupakan rangka yang berada
diluar tubuh contohnya pada hewan
invertebrata misalnya belalang kecoa
lobster kepiting yang kedua ada
endoskeleton yaitu rangka yang ditutupi
oleh otot dan kulit contohnya pada hewan
vertebrata dan manusia selanjutnya kita
akan membahas fungsi rangka atau
Skeleton pada manusia yang pertama
adalah memberi bentuk dan postur tubuh
yang kedua fungsi rangka untuk
melindungi organ-organ lunak seperti
jantung otak paru paru sumsum tulang
belakang Yang ketiga sebagai tempat
melekatnya otot-otot rangka atau otot
lurik yang biasa kita
wood dengan daging selanjutnya fungsi
rangka untuk mendukung terjadinya
gerakan yang selanjutnya untuk
hematopoiesis yaitu pembentukan sel-sel
darah di sumsum merah dan sebagai tempat
penyimpanan mineral yaitu kalsium Oke
demikian tadi materi tentang fungsi
rangka pada sistem gerak manusia
selanjutnya kita akan membahas materi
tentang rangka aksial pada sistem rangka
manusia jangan lupa like dan subscribe
ya terima kasih wassalamualaikum
