body

• Cartilage is a flexible connective tissue found at the ends of long bones to cushion them during movement.
• Bones are hard structures that protect organs, support the body, store minerals, produce blood cells, and allow movement.
• The skeletal system is made up of bones, cartilage, ligaments, tendons, joints, and muscles.
• The skeletal system consists of bones, cartilages, ligaments, tendons, joints, and muscles.
• Bones are hard structures that support the body and protect internal organs.
• There are two types of bone tissues: compact (cortical) bone and spongy ( cancellous ) bone.
• There are two types of bone tissues: compact (dense) bone and spongy (cancellous) bone.
• Compact bone has a dense structure with osteocytes embedded within lacunae surrounded by lamellae.
• Compact bone has a dense outer layer called cortex and an inner medullary cavity filled with yellow marrow.
• Spongy bone has a network of trabeculae that form a lattice-like structure and contains red marrow.
• Skeleton - The framework or structure of an organism's body
• Joints are areas where two or more bones meet and allow for movement.
• Compact bone has a dense structure with few spaces between its components.
• Compact bone tissue has a dense structure with few spaces between its components.
• Plasma Membrane


  The outermost layer of the cell that separates the cell from its environment.
• Cytoplasm


  The jelly-like substance inside the cell membrane where many cellular activities take place.
• Nucleus


  The control center of the cell where genetic information is stored.
• Ribosomes


  Small organelles found throughout the cytoplasm where protein synthesis occurs.
• Endoplasmic Reticulum (ER)


  A network of membranous tubules and flattened sacs involved in protein synthesis and processing.
• Organelles responsible for generating energy for the cell through cellular respiration.
• Lysosomes


  Organelles containing digestive enzymes that break down and recycle cellular waste and foreign substances.
• Golgi Apparatus


  A complex of flattened sacs and tubules involved in processing and packaging proteins and lipids for transport out of the cell.
• Cytoskeleton


  A network of protein filaments that provides structural support, shape, and movement to the cell.
• Plasma Membrane's Function

  Regulates cellular transport and maintains cell shape, allowing for cell signaling and metabolism.
• Cytoplasm's Composition


  Rich in water, salts, and various cellular components, making up the majority of the cell's volume.
• Nucleus's Function


  Regulates gene expression, ensuring cell survival, growth, and reproduction, and contains the cell's genetic material.
• Mitochondria's Function


  Generates most of the cell's energy through cellular respiration, producing ATP and NADH.
• Ribosomes' Function


  Responsible for translating messenger RNA (mRNA) into proteins, essential for cellular growth, repair, and response to stimuli.
• Endoplasmic Reticulum (ER)'s Function


  Involved in protein synthesis, processing, and lipid synthesis, as well as modulating cellular signaling.
• Lysosomes' Function


  Break down and recycle cellular waste, foreign substances, and cellular components, essential for maintaining cellular homeostasis.
• Golgi Apparatus' Function

  Processes and packages proteins and lipids for secretion or membrane insertion, regulating cellular signaling and secretion.
• Cytoskeleton's Function

  Provides structural support and shape to the cell, essential for cell movement, division, and cellular signaling.
