Lecture Outline & Key Timestamps ​[00:00] – Introduction & Functions of the Human Skeleton ​Structural framework, support, shape, protection (brain, spinal cord, heart/lungs), and movement. ​Role of bones in hematopoiesis (blood cell production) and mineral storage (calcium & phosphate). ​[01:31] – Primary Divisions: Axial vs. Appendicular Skeleton ​Overview of the Axial Skeleton (80 bones) vs. Appendicular Skeleton (126 bones). ​Axial Skeleton (80 Bones) ​[03:21] – The Skull (29 Bones) ​[04:14] Cranial Bones (8): Frontal, Parietal, Temporal, and Occipital bones. ​[04:58] Facial Bones (14): Structure and count of facial framework bones. ​[05:12] Auditory Ossicles (6): Malleus, Incus, and Stapes in middle ear. ​[05:34] Hyoid Bone (1): U-shaped neck bone providing attachment for tongue muscles. ​[06:03] – The Vertebral Column / Spine (26 Bones) ​Structural breakdown of vertebrae and spinal canal: ​Cervical Vertebrae (7) – Neck region. ​Thoracic Vertebrae (12) – Chest region. ​Lumbar Vertebrae (5) – Lower back. ​Sacrum & Coccyx (Tailbone). ​[07:38] – The Rib Cage / Thorax (25 Bones) ​Sternum (1) – Breastbone. ​Ribs (24 / 12 pairs): ​True Ribs (Pairs 1–7): Directly attached to sternum. ​False Ribs (Pairs 8–12): Indirectly attached via costal cartilage. ​Floating Ribs (Pairs 11–12): Protect kidneys. ​Appendicular Skeleton (126 Bones) ​[09:42] – Pectoral Girdle & Forelimbs (64 Bones) ​[10:35] Pectoral (Shoulder) Girdle: Clavicles ("collarbone") and Scapulae ("shoulder blade"). ​[11:31] Arms & Hands: Humerus, Radius, Ulna, Carpals (wrists), Metacarpals (palms), and Phalanges (fingers). ​[13:56] – Pelvic Girdle & Hindlimbs (62 Bones) ​[14:53] Pelvic Girdle: Coxal/Hip bones (Ilium, Ischium, and Pubis fusion) & Pubic Symphysis. ​[15:28] Legs & Feet: Femur (longest bone), Patella (kneecap), Tibia, Fibula, Tarsals (ankles), Metatarsals, and Phalanges (toes). ​[17:42] – Summary & Mineral Homeostasis ​Adding up all 206 bones of the human skeleton. ​Summary of bone remodeling, calcium/phosphate storage, and mineral release. #HumanSkeleton #AxialSkeleton #AppendicularSkeleton #MDCAT #NEET #Class12Biology #HumanAnatomy #Biology #MedicalStudents
