Muscular system & Nervous system

Smooth muscles are found inside our organs they work without us thinking about it, regulating things like digestion. The heart is made of cardiac muscles that pumps blood throughout our body, keeping everything running.

The muscular system is like our body's engine. It has over 600 muscles that help us move, from simple actions to more complex tasks. Skeletal muscles are attached to our bones by tendons and control our intentional movements.

Muscular System

Tendons connect the skeletal system to the muscular system by connecting muscles to bones. When muscles contract, tendons it act on bones which causes movement.

The muscular system is made up of specialized cells called muscle fibers,Their main function is contractility. Muscles attached to bones, internal organs, and blood vessels are all responsible for producing movement in the body.

Muscular Responsibility

Multiple Choice

What is the primary function of the muscular system?

• Producing movement in the body

• Digesting food

• Filtering blood

• Regulating body temperature

Multiple Choice

What connects muscles to bones in the human body?

• Ligaments

• Synovial fluid

• Tendons

• Cartilage

Multiple Choice

Which type of muscle is found in internal organs such as the stomach and intestines?

• Skeletal muscle

• Cardiac muscle

• Elastic muscle

• Smooth muscle

Concentric contractions occur when the force of contraction exceeds the force of resistance, resulting in shortening of the muscle and convergence of the muscle's origin and attachment.

Generate force

Multiple Choice

What is the process by which muscles generate force and shorten called?

• Contraction

• Relaxation

• Elongation

• Expansion

Nervous system

Nervous system

Main Function

The nervous system transmits signals between the brain and other parts of the body, including internal organs. Nervous system's activity controls our ability to move, breathe, see, think, and many more. The basic unit of the nervous system is the nerve cell or neuron.

A part of the nervous system called the autonomic nervous system controls many of the body processes like breathing, digestion, sweating, and shivering,

Autonomic

The central nervous system (CNS) is a fundamental component of the human nervous system, playing a crucial role in processing and transmitting information throughout the body. It comprises two main parts, the brain and the spinal cord.

(CNS)

​The (PNS) is further divided into the somatic nervous system, responsible for voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.

(PNS)

Multiple Choice
