A&P Unit 3 Tissues
Tissues and the Integumentary System
| Term | Definition |
|---|---|
| Integumentary | Relating to the skin and its associated structures, serving as a protective barrier. |
| Epithelial | A type of tissue that covers the body surfaces and lines cavities, playing roles in protection, secretion, and absorption. |
| Connective | Tissue that supports, binds, or separates other tissues and organs, including bone, blood, and fat tissues. |
| Muscle | Tissue responsible for movement in the body, classified into skeletal, cardiac, and smooth muscle types. |
| Nervous | Tissue that transmits nerve impulses, forming the brain, spinal cord, and nerves. |
| Histology | The study of the microscopic structure of tissues, essential for understanding their function. |
| Anatomy | The branch of science concerned with the bodily structure of living organisms. |
| Compact Bone | Dense bone tissue that provides strength and support, forming the outer layer of bone. |
| Spongy Bone | Lighter, less dense bone tissue found at the ends of long bones and in the interior of others, containing bone marrow. |
| Homeostasis | The body's ability to maintain stable internal conditions despite external changes. |
| Temperature Regulation | The process by which the body maintains its internal temperature within a certain range. |
| Sensation | The ability to perceive stimuli through sensory receptors in the skin. |
| Striations | Alternating light and dark bands found in skeletal and cardiac muscle tissues, indicating the arrangement of muscle fibers. |
| Voluntary | Movement that is consciously controlled, typically associated with skeletal muscle. |
| Involuntary | Automatic movements not under conscious control, typically associated with smooth and cardiac muscle. |
| Keratin | A fibrous protein found in the skin, hair, and nails that provides strength and waterproofing. |
| Melanin | A pigment produced by melanocytes in the skin, responsible for coloring and protection against UV radiation. |
| Sebaceous | Relating to glands in the skin that secrete oil (sebum) to lubricate and waterproof hair and skin. |
| Collagen | A structural protein that provides strength and support to connective tissues, including skin and cartilage. |
| Elasticity | The ability of tissue to return to its original shape after being stretched or deformed, important in skin and muscle. |
| Adipose | A type of connective tissue that stores fat and provides insulation and cushioning for organs. |
| Vascular | Pertaining to blood vessels; important in understanding the blood supply to various tissues. |
| Regeneration | The process of renewal or restoration of tissues, significant in healing and repair. |
| Apocrine | A type of gland that releases a portion of its cell along with its secretion, found in some sweat glands. |
| Merocrine | A type of gland that releases its secretion without losing cellular material, typical of most sweat glands. |
| Basement Membrane | A thin layer of fibrous material separating epithelial tissue from underlying connective tissue, providing support. |
| Fibroblast | A type of cell in connective tissue that produces collagen and other fibers. |
| Stratum | A layer or level within a structure; commonly used to describe layers of skin (e.g., stratum corneum). |
| Homeostatic Mechanisms | Processes that maintain equilibrium in the body, often involving feedback systems. |
| Cutaneous | Relating to or affecting the skin; often used in terms like cutaneous receptors (sensors in the skin). |
| Epi | "upon" or "over" |
| derm | "skin" |
| Myo | "muscle" |
| Osteo | "bone" |
| Neuro | "nerve" |
| blast | "germ" or "bud" |
| cyte | "cell" |
| genesis | "origin" or "creation" |
| itis | "inflammation" |
| oma | "tumor" or "swelling" |
