skeletal prelim acad weaponizer

* Support - provides structural support to the body, maintaining its shape * Protection - shields vital organs, such as the brain, heart, and lungs from injury * Movement - works in tandem with the muscles to facilitate motion in joints * Mineral storage - acts as a reservoir for calcium and phosphorus, essential for various bodily functions * Hematopoiesis - generates blood cells (red blood cells, white blood cells, platelets) in the bone marrow * Energy storage - stores lipids (fats) that can be used as energy source when needed * Joint stability - provides stable anchor points for joints, allowing controlled movement

* Skull - consists of cranial bones and facial bones * Vertebral column - consists of individual vertebrae that protect the spinal cord and provide flexibility for movement * Rib cage - composed of ribs and the sternum that encloses the heart and lungs * Auditory Ossicles - tiny bones in each ear essential for hearing

* Pectoral girdle (Shoulder girdle) - comprising the scapulae and clavicles that connects the upper limbs to the axial skeleton * Pelvic girdle (Hip girdle) - consists of the two hip bones and connects the lower limbs to the axial skeleton * Upper limbs - includes forearms, wrists, hands, and fingers * Lower limbs - includes thighs, legs, ankle, feet and toes

* Long bones - longer than they are wider, consisting of a shaft (diaphysis) and two ends (epiphysis * Short bones - cuboidal in shape * Flat bones - thin, flat, curved * Irregular bones - complex and irregular shaped bones * Sesamoid bones - small round bones that develop within tendons or ligaments * Accessory bones - not present in all individuals and are considered anatomical variations
