Connective tissue supports, binds, and protects body structures. Types include bone, cartilage, adipose, and blood, each serving unique roles like providing structural framework, storing energy, or facilitating circulation and immunity.
4.3 Muscle and Nervous Tissue: Structure and Function
Muscle tissue enables movement and includes skeletal, smooth, and cardiac types. Skeletal muscles attach to bones, facilitating voluntary movement, while smooth and cardiac muscles function involuntarily. Nervous tissue, composed of neurons and glial cells, transmits signals, enabling communication and control throughout the body. Together, these tissues coordinate movement, maintain posture, and regulate bodily functions, ensuring overall physiological harmony.
Body Systems and Their Interactions
The human body comprises interconnected systems such as skeletal, muscular, nervous, endocrine, circulatory, respiratory, and digestive, each contributing to the body’s overall functionality and coordination.
5.1 Skeletal and Muscular Systems: Support and Movement
The skeletal system provides structural support and protection, while the muscular system enables movement. Bones act as levers, and muscles generate force through contraction. Together, they facilitate posture, locomotion, and protection of vital organs. The interaction between bones and muscles, mediated by tendons and ligaments, ensures efficient movement. These systems are essential for overall mobility and stability, with their functions detailed in free PDF anatomy notes for comprehensive understanding.
5.2 Nervous and Endocrine Systems: Control and Coordination
The nervous system regulates body functions through electrical and chemical signals, enabling rapid responses. The endocrine system uses hormones for slower, long-term control. Together, they maintain homeostasis, managing processes like metabolism and growth. Free PDF resources detail how these systems interact to ensure coordinated bodily functions, essential for overall health and adaptation to environmental changes. These notes provide comprehensive insights for students studying human anatomy and physiology.
5.3 Circulatory, Respiratory, and Digestive Systems: Exchange and Absorption
