Structure of human skeleton Human skeleton is composed of bones and cartilage Bones are composed of cells known as osteocytes Osteocytes are arranged in circles and connected to each other by cytoplasmic bridges There is haversian canal between cicrles, it contains blood vessels and nerves Intracellular space is filled by matrix (ossein) that contain Ca, P, carbonate and protein. Cartilage is composed of cells chondrocytes

Formation of bone For bone formation and normal growth minerals such as Ca, P and vitamins A, C and D needed Deficiency of vitamin D causes rickets – рахит, A growth rate decreases, C causes weakness and disease scurvy – цинга Ca level in blood is regulated by hormones parathormone, released by parathyroid gland, and calcitonin, released by thyroid gland Parathormone: is secreted when Ca level is decreased in blood Calcitonin: is secreted when Ca level is increased from blood

1. Smooth muscle Each cell is long, sharp-ended with a single central nucleus Smooth muscles generally regulated by the Autonomic Nervous System (ANS) Their movement is generally irregular and slow They are found in the walls of inner organs, like stomach, intestine, blood vessels, urinary bladder etc.

Energy Supply For Muscles The energy reserve in the muscles can only supply energy for 5 seconds. During contraction, CREATIN PHOSPHATE (which supplies 20 times more energy than ATP) is used as the primary energy source. Then ATP is used as the secondary energy source. Only ATP is used during relaxation.
