Takeaways
- 🦴 The video discusses the human skeletal system, focusing on the structure and shape of bones.
- 👀 The script describes the structure of long bones, which include the epiphysis, diaphysis, and the growth plate (cakra epifisis).
- 📐 The functions of long bones are to bear the weight of the body and assist in movement, with examples given such as the humerus, femur, tibia, and fibula.
- 🔵 The script mentions short bones that are cube-shaped and provide strength and compactness in areas with limited movement, found in the wrist (carpals) and ankle (tarsals).
- 🛡 Flat bones are shaped like plates and serve to expand the surface area for muscle attachment and provide protection, located in the skull, including the facial bones, parietal bones, and sternum.
- 🌪 Irregular bones have irregular shapes and are components of the spine, such as vertebrae.
- 🔶 Sesamoid bones are small, round bones found in joints, like the kneecap (patella).

Q & A
What is the main topic discussed in the script?
-The main topic discussed in the script is the human locomotor system, specifically focusing on the structure and shapes of bones.
What are the three main parts of a long bone?
-The three main parts of a long bone are the epiphysis, diaphysis, and the articular cartilage.
What is the function of the articular cartilage found at the epiphysis of a long bone?
-The articular cartilage at the epiphysis of a long bone functions to provide a smooth surface for joint movement and to absorb shock.
What is the difference between the endosteum and periosteum?
-The endosteum is the inner lining of the bone that is in contact with the bone marrow, while the periosteum is the outer covering of the bone that contains nerves and blood vessels.
Which bones are considered long bones in the human body?
-Long bones in the human body include the humerus, radius, ulna, femur, tibia, and fibula.
What is the function of short bones?
-Short bones provide strength and stability to areas of the body that have limited movement, such as the carpal bones of the wrist and the tarsal bones of the ankle.
What is the shape of flat bones and where are they typically located?
-Flat bones are shaped like plates and are typically located in areas that need to protect internal organs or provide a broad surface for muscle attachment, such as the bones of the skull, including the frontal bone, parietal bones, and the sternum.
What is the function of irregular bones?
-Irregular bones have irregular shapes and serve various functions, including protection of internal organs and providing attachment points for muscles. An example is the vertebrae.
What are sesamoid bones and where can they be found?
-Sesamoid bones are small, round bones that are embedded within tendons and are typically found in joints. An example is the patella, which is located in the knee joint.
What will be discussed after the topic of bone shapes in the script?
-After discussing bone shapes, the script will cover the process of bone formation, known as ossification.
What is the term used for the rounded end of a long bone?
-The term used for the rounded end of a long bone is 'epiphysis'.
Outlines
🦴 Human Skeletal System Overview
The video script introduces the topic of the human musculoskeletal system, focusing on the structure and shape of bones. It begins with an explanation of the bone structure, highlighting the epiphysis, diaphysis, and the medullary cavity. The script describes the functions of these parts, such as the epiphysis being a growth plate and the medullary cavity housing bone marrow. The video then moves on to discuss the various shapes of bones, including long bones like the humerus and femur, which support body weight and facilitate movement, short bones found in the wrist (carpals) and ankle (tarsals), flat bones like those in the skull and sternum, and irregular bones like vertebrae. It also mentions sesamoid bones, which are small, round bones embedded in tendons, such as the patella. The script concludes by mentioning the upcoming discussion on bone formation or ossification.

Hai Hai assalamualaikum warahmatullahi
wabarakatuh ketemu lagi dengan saya
Widyaningsih kali ini kita masih
membahas bab sistem gerak manusia iaitu
pada materi struktur dan bentuk tulang
Oke disimak baik-baik ya yang pertama
kita akan bahas adalah struktur tulang
Coba kalian Perhatikan baik-baik gambar
tulang ini adalah gambar tulang yang
termasuk tulang pipa terdiri dari bagian
ujung yang kita sebut dengan epifisis
kemudian bagian tengah kita sebut
sebagai diafisis nah pada bagian
epifisis itu nomor satu terdapat Cakra
epifisis yang merupakan tulang rawan
kemudian dibawahnya adalah tulang spons
Hai dan bagian dalam itu nomor tiga
terdapat rongga sumsum tulang struktur
bagian dalam itu namanya endosperm dan
struktur bagian luar namanya periosteum
pada bagian epifisis itu terdapat
artikulasi atau persendian selanjutnya
kita akan membahas bentuk-bentuk tulang
nah sesuai dengan gambar ternyata ada
bermacam-macam bentuk tulang kita bahas
satu persatu ya Yang pertama adalah
bentuk tulang pipa nah kalian Perhatikan
gambar ya bentuk tulang pipa bentuknya
silindris panjang ada bagian epifisis
diafisis dan Cakra epifisis fungsi dari
tulang pipa adalah untuk menahan berat
tubuh Membantu pergerakan tulang pipa
ini terdapat pada tulang lengan atas
humerus tulang hasta ulna tulang
pengumpil radius tulang paha femur
tulang kering Tibia dan tulang betis
fibula selanjutnya bentuk tulang yang
kedua adalah tulang pendek kalian
Perhatikan gambar ya tulang pendek
berukuran pendek berbentuk kubus fungsi
dari tulang pendek adalah memberikan
kekuatan dan kekompakan pada area yang
melakukan pergerakannya terbatas tulang
pendek ini terdapat pada tulang
pergelangan tangan atau karpal dan pada
tulang pergelangan kaki atau tarsal
[Musik]
bentuk tulang yang selanjutnya adalah
Hai Kak tulang pipih kalian Perhatikan
gambar ya tulang pipih bentuknya seperti
lempengan fungsi dari tulang pipih
adalah memperluas permukaan untuk
perlekatan otot dan memberikan
perlindungan tulang pipih terdapat pada
tulang tengkorak termasuk tulang muka
tulang rusuk dan tulang dada selanjutnya
kita akan membahas tulang tidak
beraturan nah kalian Perhatikan ya
bentuk tulang tidak beraturan bentuknya
tidak beraturan tulang tidak beraturan
ini adalah penyusun tulang belakang atau
vertebra yay Nah selanjutnya kita akan
membahas bentuk tulang sesamoid
Hai pernah kalian Perhatikan gambar ya
tulang sesamoid ini adalah tulang
berukuran kecil bulat terdapat pada
persendian tulang sesamoid terdapat pada
Tulang tempurung lutut atau patella Oke
demikian tadi pembahasan tentang
struktur dan bentuk tulang selanjutnya
kita akan membahas proses pembentukan
tulang atau osifikasi jangan lupa like
dan subscribe ya terima kasih
