A hypothetical organ has the following functional requirements: (1) the ability to resist surface abrasion and mechanical stress
alukav5142 [94]

Answer:

The <u>five</u> tissues needed that could make up this hypothetical organ are stratified squamous epithelial tissue, smooth muscle tissue, dense irregular connective tissue, loose connective tissue, and nervous tissue.

Explanation:

<h3 /><h3>Ability to resist surface abrasion and mechanical stresses</h3>

Stratified squamous epithelial tissue

This consists of <em>scale-like cells</em> stacked together in layers that provide a  <u>barrier that is resistant to abrasions and wear-and-tear</u>. This is also the most common type of stratified epithelium in the body. The top layer of this tissue has two types: <u>keratinized</u>, lined with dead cells with keratin, and <u>non-keratinized</u>, also with dead cells but without the keratin. In the human body, the skin is composed of stratified squamous epithelium.

<h3>Ability to contract involuntarily when stimulated by cells of the nervous system</h3>

Smooth muscle tissue

Smooth muscle, known for its <em>non-striated appearance,</em> is a kind of <u>involuntary</u> muscle cells that are <u>stimulated by neural signals by the autonomic nervous system, hormones, and local factors</u> such as a wall stretch of a certain organ, inflammation of visceral/parietal organs, etc. In the human body, this is mostly found in the <u>walls of blood vessels and organ systems.</u>

<u />

<h3>Ability to resist tension in many different planes of force</h3>

Dense irregular connective tissue

This is a kind of connective tissue made up of <u>collagen fibers arranged randomly.</u> This creates <u>greater strength and support in all directions</u>. It can also <u>return to its original shape</u> even after stretching.

<h3>One tissue to "glue" all other tissues together</h3>

Loose connective tissue

Also known as areolar tissue, it is loosely made up of collagen, elastin, and reticular fibers, and lots of ground substance. It is arranged in a web-like fashion and serves as the "cement" which fills in spaces between tissues.

<h3>One tissue to stimulate the contracting cells</h3>

Nerve tissue

It is a specialized kind of tissue responsible for communication within the body. It transmits and receives signal impulses throughout the body. The 2 types of nervous tissues are neurons and neuroglia.
