Where does the thermoregulatory centre receive nervous impulses from regarding temperature? | The thermoregulatory centre receives nervous impulses from temperature receptors in the skin. |
Structures or organs that respond to the information from the thermoregulatory centre to help the body warm up or cool down. | Effectors |
What are effectors, and what is their role in temperature regulation? | Effectors are structures or organs that respond to information from the thermoregulatory centre to assist the body in warming up or cooling down. |
Blood vessels, sweat glands, and skeletal muscles that respond to information from the thermoregulatory centre. | Effectors in Thermoregulation |
What are examples of effectors in thermoregulation, and what information do they respond to? | Examples of effectors in thermoregulation include blood vessels, sweat glands, and skeletal muscles, and they respond to information from the thermoregulatory centre. |
The widening or dilation of blood vessels in the skin, allowing the transfer of heat energy to the environment. | Vasodilation |
What is vasodilation, and how does it contribute to thermoregulation? | Vasodilation is the widening or dilation of blood vessels in the skin, facilitating the transfer of heat energy to the environment. |
Sweat glands produce sweat, and when it evaporates from the skin, heat energy is transferred to the environment. | Sweat Glands and Thermoregulation |
How do sweat glands contribute to thermoregulation? | Sweat glands produce sweat, and when it evaporates from the skin, heat energy is transferred to the environment. |
The skin plays a crucial role in thermoregulation, with the epidermis and dermis having specific functions. | Functions of the Skin in Thermoregulation |
What are the important functions of the skin in thermoregulation? | The skin, with its layers (epidermis and dermis), has important functions in thermoregulation. |
The top layer of the skin where sweat is released and evaporates. | Epidermis and Sweat Release |
What is the role of the epidermis in thermoregulation? | The epidermis is the top layer of the skin where sweat is released and evaporates. |
The layer below the epidermis where sweat glands are found, and it also contains temperature receptors that send impulses to the hypothalamus. | Dermis and Sweat Glands |
What is the role of the dermis in thermoregulation? | The dermis, the layer below the epidermis, contains sweat glands and temperature receptors that send impulses to the hypothalamus. |
The narrowing or constriction of blood vessels in the skin, reducing heat loss. | Vasoconstriction |
What is vasoconstriction, and how does it contribute to thermoregulation? | Vasoconstriction is the narrowing or constriction of blood vessels in the skin, which reduces heat loss. |
Effector response to low body temperature, achieved through vasoconstriction, stopping sweating, and generating more heat through shivering. | Reduction of Heat Loss |
How do effectors respond to low body temperature to reduce heat loss? | Effectors respond to low body temperature by causing vasoconstriction, stopping sweating, and generating more heat through shivering. |
The rapid contraction of skeletal muscles, generating heat by releasing more energy from respiration. | Shivering |
What is shivering, and how does it contribute to generating heat in response to low body temperature? | Shivering is the rapid contraction of skeletal muscles, contributing to the generation of heat by releasing more energy from respiration. |
