1.5 Nervous System & Integumentary System

Front

What is the integumentary system?

Back

The integumentary system is the organ system that includes the skin, hair, nails, and glands, which protects the body and helps regulate temperature.

Front

How does the integumentary system help maintain homeostasis?

Back

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

Front

What are the main functions of the nervous system?

Back

The main functions of the nervous system include receiving sensory input, integrating information, and coordinating motor output.

Front

What are the three layers of the skin?

Back

The three layers of the skin are the Epidermis (outer layer), Dermis (middle layer), and Hypodermis (inner layer).

Front

What is the role of the spinal cord in the nervous system?

Back

The spinal cord transmits information between the brain and the rest of the body, controls reflexes, and coordinates motor movements.

Front

What is the function of the epidermis?

Back

The epidermis is the outermost layer of skin that provides a barrier to protect the body from the environment.

Front

What is the function of the dermis?

Back

The dermis is the middle layer of skin that contains connective tissue, blood vessels, and nerve endings.

Front

What is the function of the hypodermis?

Back

The hypodermis is the innermost layer of skin that helps insulate the body and anchors the skin to underlying structures.

Front

What is a reflex action?

Back

A reflex action is an automatic response to a stimulus that occurs without conscious thought, often involving the spinal cord.

Front

What is sensory input?

Back

Sensory input refers to the information received by the nervous system from sensory organs, such as sight, sound, touch, taste, and smell.
