Homeostasis Regulation Systems Quiz

What is the main function of the subcutaneous layer?

Which type of nerve endings are present in the subcutaneous layer that are sensitive to pressure?

Which layer of the skin is composed of keratinized stratified squamous epithelium?

What is the main function of the integumentary system listed in the text?

Which cells are NOT found in the epidermis?

What are the nerve endings sensitive to pressure in the subcutaneous layer called?

Which region of the skin contains epidermal ridges and sweat pores?

In the anatomical position, the thumb is ipsilateral to the little finger.

Your buttocks are distal to your knees.

Your right foot and right hand are contralateral to each other.

Your knee is superficial compared to your thigh.

Your lungs are anterior to your spinal column.

Your breastbone is distal to your chin.

Your calf is superficial compared to your heel.

The pericardial cavity contains the brain.

The abdominal cavity contains the stomach and liver.

The pleural cavity is a fluid-filled space that surrounds a lung.

Homeostasis and Regulation

The body has regulating systems to maintain internal balance and counteract changes
The nervous system and endocrine system work together or independently to regulate homeostasis
The nervous system uses electrical signals (nerve impulses) to counteract changes
The endocrine system uses hormones to regulate the body

Feedback Systems

Feedback systems monitor and regulate internal conditions
Three components of a feedback system: receptor, control center, and effector
Feedback systems work through negative feedback loops

Body Cavities

The body has different cavities, including the cranial cavity, vertebral canal, thoracic cavity, abdominopelvic cavity, and pelvic cavity
Each cavity has specific organs and structures within it

Anatomical Terminology

Anatomical terms are based on Greek and Latin words
Anatomical position: standing erect, facing forward, with feet flat on the floor and palms facing forward
Body regions have anatomical and common names (e.g., cephalic region = head)

Integumentary System

The integumentary system contributes to homeostasis by protecting the body and regulating body temperature
The subcutaneous layer stores fat and contains large blood vessels and nerve endings (pacinian corpuscles)

Skeletal System

The skeletal system provides support and protection for the body
Functions include supporting the body, providing surface area for muscle attachments, aiding body movements, housing cells that produce blood cells, and storing minerals and lipids

Test your knowledge on how the nervous system and endocrine system work together or independently to regulate homeostasis in the body. Explore how nerve impulses and messenger molecules play a crucial role in maintaining internal balance.
