6.1.2 Effectors

• What are effectors in biology?

  Organs responding to stimuli
• Match the effector type with its definition:

  Muscles ↔️ Contract or relax to produce movement

  Glands ↔️ Secrete chemicals like hormones
• Order the following effector types based on their functions:

  1️⃣ Muscles produce movement

  2️⃣ Glands secrete hormones
• Endocrine glands secrete hormones directly into the bloodstream
• What is the primary function of endocrine glands as effectors?

  Hormone regulation
• Which system coordinates effectors to produce physiological responses?

  Nervous or endocrine
• Match the effector type with its function:

  Muscles ↔️ Produce movement

  Glands ↔️ Secrete chemicals
• Muscles contract or relax for movement and posture.


  True
• Match the effector type with its definition and function:

  Muscles ↔️ Contract or relax to produce movement

  Glands ↔️ Secrete chemicals like hormones or enzymes
• Sequence the steps of muscle response coordination:

  1️⃣ Stimulus detected by receptors

  2️⃣ Signal transmitted to nervous system

  3️⃣ Signal sent to muscle

  4️⃣ Muscle contracts or relaxes
• What is the primary function of cardiac muscle?

  Pumps blood
• Glands secrete chemicals in response to stimuli detected by receptors.


  True
• Match the gland type with its secretion and example:

  Endocrine Gland ↔️ Hormones; Thyroid

  Exocrine Gland ↔️ Enzymes, fluids; Salivary glands
• Endocrine glands secrete hormones directly into the bloodstream.


  True
• What are the two main types of effectors in the human body?

  Muscles and glands
• How do exocrine glands secrete their products?

  Through ducts
• The two main types of effectors in the human body are muscles and glands
• Effectors work in coordination with the nervous and endocrine systems to maintain homeostasis
• The endocrine system communicates through hormones.


  True
• Steps in the response to a stimulus

  1️⃣ Stimulus is detected by receptors

  2️⃣ Signals are sent to coordination systems

  3️⃣ Effectors are activated

  4️⃣ A physiological response is generated
• What do muscles do as effectors?

  Produce movement
• The two main types of effectors are muscles and glands
• Effectors work in coordination with the nervous or endocrine system.

  True
• What type of muscle is found in the heart?

  Cardiac muscle
• What systems coordinate with muscles to respond to stimuli detected by receptors?

  Nervous system
• What type of muscle is attached to bones and responsible for movement?

  Skeletal muscle
• Where is smooth muscle found in the body?

  Internal organs
• What type of chemicals do glands secrete in response to stimuli?

  Hormones or enzymes
• Which glands secrete enzymes or fluids through ducts?

  Exocrine glands
• Exocrine glands deliver their secretions to specific locations through ducts
• Cardiac muscle is responsible for digestive processes in the stomach.

  False
• Which systems coordinate effectors to maintain homeostasis?

  Nervous and endocrine
• Steps in how effectors produce responses to stimuli:

  1️⃣ Receptors detect stimulus

  2️⃣ Signals sent to nervous or endocrine system

  3️⃣ Effectors are activated

  4️⃣ Physiological response occurs
• The nervous system uses neurotransmitters to transmit signals from neurons to effectors
• Which neurotransmitter is released by the sympathetic nervous system during stress?

  Adrenaline
• What role do effectors play in homeostasis?

  Restore balance
• Which physiological processes are regulated by hormones secreted by glands?

  Metabolism, growth
• The two main types of effectors are muscles and glands
• Effectors respond to stimuli without any coordination from the nervous or endocrine systems

  False
• What is the role of glands in the body as effectors?

  Secrete hormones or enzymes
