Lab Quiz #1

areolar/loose connective tissue

Loose packing >> allows for support >> attaches to skin underlying the tissues >> key location is the epidermis

simple squamous

Single layer of cells, flatten and found in alveoli of the lungs

In alveoli is where CO2 and O2 exchanges >> the flatten of cell is what allow the exchange

stratified squamous

* can have a layer of keratin 
* protection against abrasion i.e. eating having multiple layers is beneficial 
* (SKIN, ESOPHAGUS)

simple cuboidal

* straight nucleus side by side
* Thyroid, salivary gland, ducts

\

simple columnar(with microvili)

* duodenum, trachea

pseudostratified columnar

* cillia
* dense irregular connective tissue

transitional epithelium

* lamia propria
* transitional epithelium

muscle tissue

three types


1. cardiac muscle
2. skeletal muscle
3. smooth muscle

60% of the body mass of a well-conditioned human

skeletal muscle

striated, voluntary muscle,

myocytes or muscle fibers

striated extremely long and thick

sarcomeres

**Contractile elements**

smooth muscle

* involuntary, found in the digestive system
* easily maintain sustained contraction
* mononucleated and lack visible striations

Cardiac muscle

* involuntary and mononucleated
* cardiac myocyes are self-excitatory( no signal needed)
* Branching and tightly bonded

**Neurons**

**nerve cells designed to receive, integrate and transmit signals**

**Sensory transduction**

**conversion of a physical stimulus to chemical and electrical signals.(putting hands in a fridge)**

**Dendrites**

* **cell processes that serve to receive and integrate incoming information from other neurons.(feeling in the body)**

**Axon**

* **Nerve fiber that sends outgoing information to other neurons or muscles.**

**Peripheral nerves**

**consist of bundles of axons**

male reproductive tissue

Testes

female reproductive tissue

ovaries

circulatory system tissue

artery, vein, nerve

female reproductive

oocytes

fibrous(dense regular tissue)

densely packed with collagen fibers.

makes up tendons(bone-muscle)

ligament(bone-bone)

hyaline cartilage

Smooth glassy appears > thick ground >> hyaluronic acid

End of growthing long bone

cancellous bone

flat bones

adipose

* **Extracellular matrix occupies much less space than the cells. (fat) is deposited intracellularly.**
* **under the skin, in the buttocks, breasts and abundant in the omentum in the abdomen.**

Dense irregular connective tissue

contains collagen fibers arranged into irregular, interwoven bundles.

**White/ Yellow Adipose Tissue:**

Fat cells, nuclei is pushed up against the side >> in adipose there is only one nuclei
