Study Notes
Definition and Classification
- Tissue: a group of similar cells that perform a specific function
- Classified into four main categories:
- Epithelial tissue: forms the lining of organs, glands, and other body surfaces
- Connective tissue: provides support, structure, and connectivity to the body
- Muscle tissue: responsible for movement and contraction
- Nervous tissue: transmits and processes information
Characteristics of Tissue
- Cellularity: tissues are composed of cells
- Specialization: each type of tissue has a specific function
- Organization: tissues are organized into organs and organ systems
- Adaptability: tissues can adapt to changes in the body
Functions of Tissue
- Protection: epithelial tissue protects the body from external damage
- Support: connective tissue provides structural support
- Movement: muscle tissue enables movement and contraction
- Communication: nervous tissue transmits and processes information
Definition and Classification of Tissue
- A group of similar cells performing a specific function is called tissue
- Four main categories of tissue exist:
- Epithelial tissue: forms lining of organs, glands, and body surfaces
- Connective tissue: provides support, structure, and connectivity
- Muscle tissue: responsible for movement and contraction
- Nervous tissue: transmits and processes information
Characteristics of Tissue
- Tissues are composed of cells, exhibiting cellularity
- Each tissue type has a specific function, displaying specialization
- Tissues are organized into organs and organ systems, showing organization
- Tissues can adapt to changes in the body, demonstrating adaptability
Functions of Tissue
- Epithelial tissue provides protection from external damage
- Connective tissue offers structural support to the body
- Muscle tissue enables movement and contraction
- Nervous tissue facilitates communication through information transmission and processing
Tissue
Connective Tissue
- Provides support, structure, and connectivity to the body, binding and supporting organs and tissues
- Transports nutrients and waste, stores energy reserves, and regulates body temperature
- Consists of three types:
- Loose connective tissue (e.g., fat, areolar tissue)
- Dense connective tissue (e.g., bone, cartilage, tendons)
- Specialized connective tissue (e.g., blood, bone marrow, adipose tissue)
Epithelial Tissue
- Forms the lining of organs, glands, and body surfaces, protecting the body from external damage
- Regulates the exchange of substances and produces and secretes hormones and other substances
- Classified into three types:
- Simple epithelial tissue (e.g., skin, lung, gut lining)
- Stratified epithelial tissue (e.g., skin, oral mucosa)
- Pseudostratified epithelial tissue (e.g., respiratory tract)
Muscle Tissue
- Responsible for movement and contraction, moving the body's skeleton
- Regulates body temperature, maintains posture and balance
- Comprises three types:
- Skeletal muscle (voluntary, striated)
- Smooth muscle (involuntary, non-striated)
- Cardiac muscle (involuntary, striated)
Nervous Tissue
- Responsible for transmitting and processing information, receiving and transmitting sensory information
- Integrates and processes information, controlling and coordinating body functions
- Consists of three types:
- Neurons (nerve cells)
- Neuroglial cells (supporting cells)
- Sensory receptors (e.g., photoreceptors, mechanoreceptors)
