Study Notes
Levels of Organization
- Atoms are composed of subatomic particles: protons, electrons, and neutrons.
- Molecules form when two or more elements combine; examples include water, proteins, and sugars.
- Molecules serve as the basic building blocks for all bodily structures.
Basic Structure of the Human Body
- Chemical Level: Involves atoms and molecules, the fundamental components of matter including elements like Hydrogen, Oxygen, Carbon, Nitrogen, Calcium, and Iron.
- Cellular Level: The smallest unit of living matter, with diverse sizes and functions; humans are multicellular organisms.
Connective Tissues
- Ligaments: Connective tissue bands connecting bone to bone, made up of collagen (unstretchable) and elastic fibers (stretchable).
- Tendons: Connect bone to muscle.
Musculoskeletal System
-
Muscle Types:
- Skeletal Muscles: Voluntary and striated, enabling body movement.
- Smooth Muscles: Involuntary and non-striated.
- Cardiac Muscle: Involuntary and striated, specific to the heart.
Joints and Articulations
- Joints are points connecting two or more bones, classified into:
- Fibrous Joints: Joined by fibrous tissue.
- Cartilaginous Joints: Joined by hyaline cartilage or fibrocartilage.
- Synovial Joints: Feature a joint cavity and hyaline cartilage coverage.
Bursae and Synovial Sheath
- Bursae: Closed fibrous sacs lined with smooth membranes, found in areas where tendons interact with bones, offering lubrication.
- Synovial Sheath: Tubular bursa that surrounds tendons.
Body Cavities
- Abdominopelvic Cavity: Divided into abdominal (liver, stomach, intestines) and pelvic (bladder, reproductive organs) regions.
- Pericardium: Covers the heart.
Peripheral Nervous System (PNS)
- Comprises cranial nerves, spinal nerves, and ganglia, excluding the spinal cord.
Structures Related to the Nervous System
- Somatic Nervous System: Controls voluntary movements, particularly in skeletal muscles.
Additional Anatomical Terms
- Deep Fascia: Connective tissue layer covering muscles and deep structures.
- Superficial Fascia: Connects dermis of skin to underlying tissues.
