1.1.1 Major bones in the human body

• The skeletal system stores minerals and protects vital organs.

  True
• Flat bones are thin and flattened, protecting internal organs and providing muscle attachment points, such as the ribs and scapula.
• How many vertebrae are in the cervical region of the spine?

  7
• Match the bone type with its key feature:

  Long Bones ↔️ Cylindrical shape

  Short Bones ↔️ Cube-like structure

  Flat Bones ↔️ Thin, flattened shape

  Irregular Bones ↔️ Complex, asymmetrical shape
• The irregular bones provide attachment points for muscles and ligaments, such as the vertebrae.
• Short bones have a cube-like shape and provide stability and support
• Irregular bones have symmetrical shapes and provide stability for joints.

  False
• What is the main function of short bones in the skeletal system?

  Provide stability
• Where are irregular bones commonly found in the body, and what is their primary function?

  Vertebrae, muscle attachment
• The cranium consists of 8 bones, including the frontal, parietal, temporal, and occipital
• Match the spinal region with its number of vertebrae:

  Cervical ↔️ 7

  Thoracic ↔️ 12

  Lumbar ↔️ 5

  Sacral ↔️ 5 fused
• The sacral vertebrae are fused and connect the spine to the pelvis.

  True
• The ribs attach to the vertebrae and facilitate breathing
• The vertebrae provide structural support and attachment points for the ribs.


  True
• The scapula is a flat, triangular bone that provides attachment points for upper limb muscles
• What is the function of the humerus in the upper arm?

  Leverage for movement
• The humerus is a long bone in the upper arm
• The phalanges are the bones in the fingers
• The skeletal system protects vital organs.


  True
• How many bones are in the cranium?

  8
• The facial bones include the maxilla and the mandible
• Match the spinal region with its key function:

  Cervical ↔️ Supports the head

  Thoracic ↔️ Protects the heart and lungs

  Lumbar ↔️ Supports lower back

  Sacral ↔️ Connects spine to pelvis

  Coccygeal ↔️ Pelvic support
• The coccygeal region consists of fused vertebrae.


  True
• What is the primary function of the ribs?

  Protect organs
• Match the bone of the pectoral girdle with its primary function:

  Clavicle ↔️ Connects scapula to sternum

  Scapula ↔️ Forms part of shoulder joint
• The pectoral girdle connects the upper limbs to the axial skeleton.
• The humerus is a long bone in the upper arm.
• There are 8 carpals in the wrist.
• Match the pelvic girdle bone with its primary function:

  Ilium ↔️ Supports body's weight

  Ischium ↔️ Provides attachment points for leg muscles

  Pubis ↔️ Connects hip bones
• The femur is the longest and strongest bone in the body.
• The tarsals are the 7 bones in the ankle.


  True
• Match the bone type with its primary function:

  Long Bones ↔️ Provide leverage for movement

  Short Bones ↔️ Provide stability and support

  Flat Bones ↔️ Protect internal organs

  Irregular Bones ↔️ Provide attachment points
• Order the regions of the spine from top to bottom:

  1️⃣ Cervical

  2️⃣ Thoracic

  3️⃣ Lumbar

  4️⃣ Sacral

  5️⃣ Coccygeal
• What is the skeletal system composed of?

  Bones and cartilage
• Flat bones protect internal organs and provide attachment points for muscles, such as the ribs and skull bones.
• What is the shape of long bones, and what is an example of one in the human body?

  Cylindrical, femur
• What is the primary function of flat bones, and what is an example of one?

  Protect internal organs, ribs
• Long bones have a cylindrical shape with a shaft and two ends
• Flat bones are primarily located in the limbs and provide leverage for movement.

  False
• Groups of bones in the skull

  1️⃣ Cranium

  2️⃣ Facial Bones
