Question 29

- Skin - More ground substance - Provides support and helps to protect organs, muscles, and many other tissues - Contains all three types of fibers

Answer 29

Areolar Connective Tissue

Question 30

- Heart, stomach, liver - Globular area - Nucleus is at the side - Extends throughout the body - Known as the body fats

Answer 30

Adipose Tissue

Question 31

- Aorta - Consists of fibroblasts and densely compacted parallel bundles of fibers –mainly elastic fibers - Provides elasticity and resilience to the tissues

Answer 31

Elastic Connective Tissue

Question 32

- Tendon - Uniform alignment of fibers - Mainly made up of collagen fiber - Collagen fibers are packed together - Allows tissue to return to its original length after stretching

Answer 32

Dense Regular Connective Tissue

Question 33

- Skin (dermis) - A 3-dimensional structure that can withstand significant force from different directions

Answer 33

Dense Irregular Connective Tissue

Question 34

- Joints, respiratory tract - White semi-solid orientation cell - Helps your bones move smoothly past each other in your joints

Answer 34

Hyaline Cartilage

Question 35

- Supports parts of your body that need to bend and move to function - Most flexible - mainly in the larynx, the external part of the ear (pinna), and the tube leading from the middle part of the ear to the throat (eustachian or auditory tube)

Answer 35

Elastic Cartilage

Question 36

- Predominantly in the intervertebral disks of the spine and at the insertions of ligaments and tendons. - Act as a cushion within joints, where it helps manage compression forces and reduces stress placed on joints

Answer 36

Fibrocartilage

Question 37

- Support and protection of soft tissues, calcium, and phosphate storage and harboring of bone marrow - Production of blood cells

Answer 37

Bone

Question 38

- A fluid connective tissue - Deliver oxygen and nutrients to various cells and tissues of the body

Answer 38

Blood Cell

Question 39

- Multinucleated (peripherally located) - Striation - Voluntary - Very long, cylindrical cells - Attached to bones - Contract to produce movement, sustain body posture and position, maintain body temperature, store nutrients, and stabilize joints

Answer 39

Skeletal Muscle

Question 40

- Uninucleate - 1 fiber - Striated - Cylindrical cells - In the heart - Under involuntary control - Responsible for the contractility of the heart and, therefore, the pumping action

Answer 40

Cardiac Muscle

Question 41

- Fusiform shape - 1 fiber / uninucleate - Involuntary control - In the walls of hollow organs, blood vessels, eyes, glands, skin - Spindle shape - Helps with digestion and nutrient collection - Exists throughout the urinary system, where it functions to help rid the body of toxins and works in electrolyte balance

Answer 41

Smooth Muscle

Question 42

- Fundamental unit of the brain - Responsible for receiving sensory input from the external world - For sending motor commands to our muscles - For transforming and relaying the electrical signals at every step in between.

Answer 42

Neuron
