5.5 Nervous System & Integumentary System

What are the functions of the spinal cord?

• Filtering blood, storing nutrients, and producing bile

• Digesting food, regulating body temperature, and producing hormones

• Pumping blood, exchanging gases, and regulating blood pressure

• Transmitting nerve signals, controlling reflexes, and coordinating motor movements

Name the layers of the skin and briefly describe each layer.

• Epidermis, Dermis, Hypodermis

• Top layer, Middle layer, Bottom layer

• Outer layer, Inner layer, Under layer

• Surface layer, Deep layer, Subcutaneous layer

What are the main functions of the nervous system?

• Receiving sensory input, integrating information, and coordinating motor output

• Transporting oxygen, removing waste, and fighting infections

• Filtering blood, producing hormones, and storing nutrients

• Digesting food, regulating body temperature, and controlling muscle movement

Explain the role of the integumentary system in maintaining homeostasis.

• The integumentary system helps regulate body temperature, protects against pathogens, and provides sensory information to the nervous system.

• The integumentary system plays a role in producing hormones

• The integumentary system helps with digestion and nutrient absorption

• The integumentary system is responsible for pumping blood throughout the body

How does the spinal cord contribute to the nervous system?

• It has no role in the nervous system

• It helps with digestion

• It regulates body temperature

• It transmits information between the brain and the rest of the body.

Describe the function of the epidermis in the integumentary system.

• Acts as a barrier to protect the body from the environment

• Transmits electrical signals

• Regulates body temperature

• Provides nutrients to the body

What is the role of the nervous system in controlling body movements?

• It sends signals from the brain to the muscles, coordinating and regulating their actions.

• It is responsible for digestion and metabolism

• It only controls breathing and heart rate

• It has no role in controlling body movements

Discuss the importance of the dermis layer in the skin.

• It is responsible for digestion and nutrient absorption

• It contains blood vessels, nerves, hair follicles, and sweat glands, which are essential for regulating body temperature, sensation, and providing nutrients to the skin.

• It does not contain any important structures

• It is the outermost layer of the skin

How does the nervous system help in responding to external stimuli?

• By receiving sensory input from the environment, processing the information, and sending signals to the muscles and glands to produce a response.

• By controlling the body's temperature

• By producing hormones to respond to stimuli

• By regulating the digestive system

Explain the function of sweat glands in the integumentary system.

• Regulate body temperature by producing sweat

• Produce hormones to regulate metabolism

• Produce blood cells to support the immune system

• Produce oil to keep the skin moisturized
