The Integumentary system, which is primarily comprised of the skin, hair, and nails, has several crucial functions, including protection, sensory perception, temperature regulation, and vitamin D synthesis.

Interaction with other systems

The Integumentary system benefits the immune system, as the skin is the first line of defense against bacteria and infections.

Skin Diseases

sriversonjstafford — 2025-05-08 13:40:28 UTC

Primarily caused by excessive sun exposure, skin cancer is the most common form of cancer. By disrupting the normal growth and function of cells, cancerous tumors begin to form on the skin. While skin cancer is a broad term that encompasses all different types of it, Melanoma is the most serious form. Early stages of skin cancer are generally treated with minor surgery, but if it becomes too severe, chemotherapy is the typical treatment.

Something I Learned

I was surprised when I learned how complex the skin was, with its three protective layers and their interaction with other body systems, before I thought the skin was just a protective wrap around everything else.

Comprised of its 206 bones, the skeletal system is the main support structure of the body. The bones provide support and crucial protection to the internal organs.

Interaction with other systems

Tendons, which connect bone and muscle, allow the skeletal and muscular systems to work together to provide movement.

Skeletal diseases

sriversonjstafford — 2025-05-08 15:31:40 UTC

Often caused by either old age or a calcium deficiency, osteoporosis is one of the most dangerous and common bone diseases. Osteoporosis causes the bones to become very weak as it makes the bones thinner and less dense. At first, there are typically no symptoms, but as time goes on, people start to feel back pain, and their bones become prone to fractures or breaks. Treatment can help, but there is no cure.

Something I Learned

I was surprised to learn that bones have the spongy insides, I always thought they were just hollow.

With over 600 muscles, the muscular system provides nearly all bodily functions, such as movement, vision, and hearing. There are three types of muscle: cardiac, smooth, and skeletal. Skeletal muscles interact with the skeleton, and allow movement, cardiac muscles comprise the heart, and smooth muscles line the organs.

Muscles and bones cooperate to create the most essential component of the human body, movement. Tendons connect muscle and bone, allowing them to work together.

Muscular Diseases

sriversonjstafford — 2025-05-12 14:11:51 UTC

The most common muscle problem is a sprained muscle, which occurs when a muscle is overused, causing the strands of muscle fiber to stretch beyond their limit, and tear.

Something I Learned

I was surprised to learn that the heart is a muscle, and it was interesting to learn that the heart was both a muscle and an organ.

Functions

The nervous system, which is composed of the brain, spinal cord, and nerves, is the body's command center. The nervous system operates by relaying messages throughout the body, controlling functions such as movement, stress response, wound healing, and digestion.

Interaction with other systems

sriversonjstafford — 2025-05-13 14:46:20 UTC

The skeletal system provides crucial protection to the otherwise fragile nervous system. Our thick skull protects the brain from damage, and bones provide the calcium that is essential to our nervous system.

Nervous Diseases

sriversonjstafford — 2025-05-13 14:52:56 UTC

Nervous system diseases are some of the most detrimental and difficult to treat. One of the most common disorders is Alzheimer's, a horrible illness where the brain's connections slowly degenerate and die, which destroys your memory and brain function. The main symptoms are memory loss and confusion. It is, unfortunately, very common and is especially prevalent in older people. Treatment can temporarily alleviate some symptoms, but there is no cure.

Something I Learned

sriversonjstafford — 2025-05-13 14:57:01 UTC

The nervous system was my favorite subject to learn in the class. While it was complex, it was very interesting to learn about the autonomic nervous system and how the brain automatically maintains intricate bodily functions without conscious thought.

Functions

The five senses are vision, hearing, touch, smell, and taste, all of which are quite self-explanatory. The five senses are essential to human survival and function.

Interaction with other systems

sriversonjstafford — 2025-05-13 15:10:48 UTC

Each of the senses are a component of the nervous system. When stimulation to the senses are detected, the signals are referred directly to the brain.

Special Sense Diseases

sriversonjstafford — 2025-05-13 15:14:17 UTC

Any injury to one of the senses is quite a disability, while you can probably live without smell or taste, the other three are much more crucial to your survival. As you get older, your senses become less alert and lose some of their function. Usually, hearing is one of the first senses to go, in a very common illness called deafness. While you can go deaf at any age, it is much more common for older people to be hard of hearing. The curability depends on what is causing you to go deaf, but it is generally remedied with hearing aids or minor surgery.

Something I Learned

sriversonjstafford — 2025-05-13 15:17:01 UTC

It was interesting to learn of the signals relayed first from the stimulus to the senses, then to the nervous system, and into the brain. The bodies interconnectivity between the systems is fascinating.
