connective tissue
, blood vessels, oil and sweat glands, nerves, hair follicles, and other structures. It is made up of a thin upper layer called the papillary dermis, and a thick lower layer called the reticular dermis.
What tissue type makes up the dermis and how does that connect to its function?
Explanation: Our skin has two principal layers : epidermis and dermis. The epidermis is composed of epithelial tissue, and the dermis is
connective tissue
. The dermis supports the epidermis and binds it to the subcutaneous tissue (hypodermis), the loose connective tissue directly under the skin.
What are connective tissues?
Tissue that supports, protects, and gives structure to other tissues and organs in the body
. … Connective tissue is made up of cells, fibers, and a gel-like substance. Types of connective tissue include bone, cartilage, fat, blood, and lymphatic tissue.
What characteristics can be used to differentiate bone and cartilage?
They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces.
Bone is highly vascularised, and its calcified matrix makes it very strong

What two major layers constitute the dermis and what components are in each layer?
What two major layers constitute the dermis,and what components are in each layer? the papillary layer which consists of loose connective tissue and contains capillaries and sensory neurons, and
the reticular layer which consists of dense irregular connective tissue and bundles of collagen fibers
.
What type of tissue is found in the subcutaneous layer?
Subcutaneous tissue is the deepest layer of your skin. It’s made up mostly of
fat cells and connective tissue
. The majority of your body fat is stored here.
What type of connective tissue makes up the dermis?
The dermis is mostly composed of
dense irregular connective tissue
that is divided to two layers: the papillary layer and reticular layer. Interwoven within these layers are numerous elastin and collagenous fibers, produced by fibroblasts (Figure 5.6).
Which of the following are characteristics of the dermis?
The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. The nerve endings sense
pain, touch, pressure, and temperature
.
What is the main function of dermal papillae?
You should notice that the dermis extends up into the epidermis in structures called dermal papillae. These have two functions. First, they
help adhesion between the dermal and epidermal layers
. Second, in areas of thick skin like this, they provide a large surface area, to nourish the epidermal layer.
What is the function of the dermal papillae quizlet?
What is the purpose of dermal papillae?
They increase the area of contact between the dermis and epidermis, allowing for a stronger connection between the two layers
. Each dermal papillae contains the capillaries that supply nutrients to the epidermal cells.
What function does the dermis have in relation to the epidermis?
What function does the dermis have in relation to the epidermis? The dermis
contains blood vessels that supply oxygen and nutrients to its cells and those
to the epidermis as well.
What makes the dermis layer strong and elastic?
Collagen and Elastin
The dermis is held together by a protein called collagen, made by fibroblasts. Fibroblasts are skin cells that give the skin its strength and resilience. Collagen is a tough, insoluble protein found throughout the body in the connective tissues that hold muscles and organs in place.
Is cartilage a connective tissue?
Cartilage is a
form of connective tissue
in which the ground substance is abundant and of a firmly gelated consistency that endows this tissue with unusual rigidity and resistance to compression. The cells of cartilage, called chondrocytes, are isolated in small lacunae within the matrix.
Are tendons connective tissue?
A tendon is a
fibrous connective tissue that attaches muscle to bone
. Tendons may also attach muscles to structures such as the eyeball.
What connective tissue makes up the intervertebral discs?
Fibrocartilage
is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
What makes up the papillary layer?
The papillary layer is defined by rete ridges (i.e. papillae) which are finger-like structures extending into the epidermis and contains
thin collagen fibres, sensory nerve endings, cytoplasms and a rich network of blood capillaries
.
What are the connective tissues quizlet?
- Areolar Connective Tissue (Loose) …
- Adipose Tissue (loose) …

- Elastic Cartilage.
What distinguishes the epidermis from the dermis?
Dermis and epidermis are basically protective outer layers of the body. The main difference between dermis and epidermis is that
dermis is a tissue below the epidermis, containing living cells whereas epidermis is the outermost part of the body
, protecting it from dehydration, trauma, and infections.
What connective tissue contains loose arrangement of elastic and collagen fibers?
Loose Connective
Tissue
Loose (areolar)
connective tissue has a sparse, irregular network of collagen and elastic fibers suspended within a relatively large amount of ground substance.
What are the characteristics of connective tissue?
Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components:
cells, large amounts of amorphous ground substance, and protein fibers.
What is the function of elastic connective tissue?
Elastic Connective Tissue
The main fibers that form this tissue are elastic in nature. These fibers
allow the tissues to recoil after stretching
. This is especially seen in the arterial blood vessels and walls of the bronchial tubes.
What is the main tissue of the epidermis quizlet?
What type of tissue is the epidermis composed of?
Stratified Squamous Epithelium
. The epidermis is made up of stratified squamous epithelium. This stratification provides functional boundaries within the epidermis.
What characteristic can be used to differentiate between bone and cartilage quizlet?
fibrocartilage. What characteristic can be used to differentiate bone and cartilage?
The cells in bone tissue are found scattered throughout the matrix and are not connected to each other
. What carries oxygen in the blood?
What is the main difference between bone tissue and cartilage tissue?
Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is a soft, elastic and flexible connective tissue that
protects the bone from rubbing against each other
. Bones are of two types: compact or spongy.
How does cartilage differ from other connective tissues?
Cartilage is a flexible connective tissue that differs from
bone
in several ways; it is avascular and its microarchitecture is less organized than bone. Cartilage is not innervated and therefore relies on diffusion to obtain nutrients. This causes it to heal very slowly.
Which of the following are found in the dermis of the skin quizlet?
Directly beneath the epidermis is the dermis. The dermis consists of
connective tissue, nerve cells, muscle fibers, sweat glands, oil glands, and hair follicles
. Below the dermis layer is the subcutaneous layer, a layer of connective tissue that stores fat and helps the body retain heat.
What types of tissues make up the epidermis the dermis and subcutaneous layer?
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains
tough connective tissue
, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
Which of the following are found in the dermis?
The dermis contains
hair roots, sebaceous glands, sweat glands, nerves, and blood vessels
. The hypodermis lies below the dermis and contains a protective layer of fat.
