Study Notes
Cells and Tissues
- Cell Membrane: semi-permeable, regulates what enters and leaves the cell
-
Cellular Organelles:
- Nucleus: contains DNA
- Mitochondria: generates energy for the cell
- Endoplasmic Reticulum: protein synthesis and transport
- Lysosomes: cellular digestion and recycling
-
Tissue Types:
- Epithelial: forms lining of organs and glands
- Connective: supports and connects body tissues
- Muscle: contracts to produce movement
- Nervous: transmits and processes information
Organs and Organ Systems
-
Organ Systems:
- Nervous: brain, spinal cord, and nerves
- Circulatory: heart, blood vessels, and blood
- Respiratory: lungs, trachea, bronchi, and diaphragm
- Digestive: mouth, esophagus, stomach, small intestine, and large intestine
-
Organ Structure:
- Epithelial lining
- Connective tissue framework
- Muscle layers (smooth, skeletal, or cardiac)
- Nervous tissue (in some organs)
Integumentary System
-
Functions:
- Protects the body from external damage
- Regulates body temperature
- Aids in the senses of touch and feel
- Helps to regulate water loss
-
Skin Layers:
- Epidermis: outermost layer, protects against water loss
- Dermis: layer of connective tissue, contains blood vessels and nerve endings
- Hypodermis: subcutaneous layer, attaches skin to underlying tissues
Skeletal System
-
Functions:
- Supports the body
- Protects internal organs
- Provides movement and stability
- Produces blood cells
-
Bone Types:
- Long bones: humerus, femur, tibia, and fibula
- Short bones: carpals, tarsals, and metacarpals
- Flat bones: cranium, sternum, and ribs
- Irregular bones: vertebrae, pelvis, and sacrum
Muscular System
-
Types of Muscle:
- Skeletal muscle: voluntary movement
- Smooth muscle: involuntary movement (e.g., in digestive tract)
- Cardiac muscle: involuntary movement (e.g., in heart)
-
Muscle Functions:
- Movement and stabilization
- Maintaining posture
- Regulating body temperature
- Assisting in circulation and respiration
