Muscular Training Flashcards
Formation of blood cells
Hemopoiesis
Cortical bone
aka Compact. Dense outer layer. Attach to tendons
Trabecular bone
aka spongy. Honeycomb-like inner structure
Diaphysis
Shaft of long bone
Epiphysis
Ends of long bone
Periosteum
Dense outer surface of bone
Wolff’s law
Changes in bone structure coincide with changes in bone function. When the skeleton is subjected to stressful forces, it responds by laying down more bone tissue, increasing density.
Axial Skeleton
Skull, vetrebral column, sternum and ribs
Protects CNS and organs of thorax
Appendicular Skeleton
Bones of upper and lower limbs, shoulder and pelvic girdle
Articulations
Main types of joints: fibrous, cartilaginous, and synovial (most common)
Movements of synovial joints
Flexion, extension, abduction, and adduction
Central Nervous System
Brain and spinal cord
Peripheral nervous system
All nervous structures located outside of the CNS (nerves and ganglia)
Autonomic nervous system
Made up of nerves that transmit impulses to the the smooth muscles, cardiac muscle, and glands
Somatic nervous system
Under conscious control and carries nerve impulses from the CNS to the skeletal muscles
