Joint movements, also known as joint actions or articulations, refer to the various ways in which bones interact and move at the points where they meet. These movements are essential for a wide range of activities, from basic everyday tasks to complex athletic maneuvers. There are several types of joint …

A joint, also known as an articulation, is a structure in the body where two or more bones meet and interact. Joints play a crucial role in allowing movement, providing stability, and supporting various musculoskeletal system functions. They are classified into different types based on their structure and degree of …

A neuromuscular junction is a specialized synapse or connection between a motor neuron and a muscle fiber. It is a crucial site for communication between the nervous system and the muscular system, where the motor neuron releases neurotransmitters, such as acetylcholine, to stimulate the muscle fiber, leading to muscle contraction. …

Muscle contraction is a complex physiological process that involves the activation of muscle fibers, resulting in the shortening of the muscle and the generation of force. It plays a fundamental role in various physiological functions, including movement, posture maintenance, and the regulation of many bodily processes. Here’s a detailed note …

Skeletal muscle, also known as striated or voluntary muscle, is muscle tissue that individuals can consciously control. It attaches to the skeleton and enables voluntary movements like walking, running, jumping, and lifting. Skeletal muscles display a striped appearance under a microscope due to the orderly arrangement of muscle fibers. They …

Axial Skeleton The axial skeleton forms the central axis of the human body and includes bones along the midline. It provides support and protection for vital organs and plays a role in posture and movement of the head and trunk. Here are the key bones and their functions in the …

Bones make up the skeleton in vertebrates, including humans. They provide structure, protect organs, facilitate movement, produce blood cells, and store minerals like calcium and phosphorus. Bones are dynamic, adapting to activity and metabolic needs. The human skeleton is a complex framework for stability and mobility. Types of bones Bones …

The skeletal system, commonly known as the skeleton, forms the anatomical framework of bones and cartilage that offers structural support and shape to the human body. It acts as a protective and supportive structure for internal organs, enables bodily movement through muscle attachment, participates in blood cell production, and stores …
