Study Notes
Basic Concepts in Cell Biology
- The fundamental unit of life is the cell.
- Cells are surrounded by a watery medium called extracellular fluid.
- The plasma membrane provides structural support, regulates exchanges, and isolates the cell from the environment.
Cellular Structures and Functions
- Microfilaments are responsible for muscle contraction.
- Ribosomes are primarily found attached to the endoplasmic reticulum, particularly in the rough ER where protein synthesis occurs.
- Mitochondria are the organelles responsible for energy production.
- The Krebs cycle takes place in the mitochondrial matrix.
- Lysosomes break down waste materials and damaged organelles.
Cellular Processes
- Simple diffusion does not require ATP, while active transport, endocytosis, and exocytosis do.
- The cytoskeleton provides structural support and shape to the cell.
- Gap junctions enable communication between cells.
Tissue Types and Functions
- Epithelial tissue lines body surfaces and cavities.
- Simple squamous epithelium is specialized for diffusion and filtration.
- Simple columnar epithelium is adapted for absorption, particularly in the small intestine.
- The main function of connective tissue is protection and support.
Connective Tissue
- Adipose tissue stores energy and provides insulation.
- Cartilage is avascular and contains chondrocytes but does not regenerate quickly.
- The nervous tissue transmits electrical impulses.
Skin and Glandular Structures
- The epidermis protects against UV radiation.
- Eccrine glands produce sweat, while the stratum basale is the deepest layer of the epidermis.
- The dermis contains dense irregular connective tissue.
Bone Structure and Function
- The primary functions of the skeletal system are movement and support.
- The long shaft of a bone is known as the diaphysis.
- Osteoblasts are responsible for bone formation; yellow bone marrow primarily functions for fat storage.
- The axial skeleton includes the skull, vertebrae, and ribs.
Bone Types and Joint Characteristics
- Ossification is the process of forming bone tissue.
- Bones of the cranium are classified as flat bones; the patella is a sesamoid bone.
- The bones of the wrist are referred to as carpals.
- The red bone marrow in bones produces red blood cells.
- The most common joint type in the body is the synovial joint.
Joint Classifications
- The joint between skull bones is categorized as a suture, which is a type of fibrous joint.
