Unit 2 Tissues (Anatomy)

(pictures + functions + locations + characteristics included)

Stratified squamous epithelium:

(Many layers of flattened cells)

Fibrocartilage:

(Blue Pic: Notice the dense arrangement of the fibers and the chondrocytes that look similar to the ones in hyaline cartilage ↓)

Dense irregular connective:

(Notice the pattern isn't parallel, it's MANY directions ↓)

Dense regular connective:

(Notice how the fibers are running parallel to each other ↓)

Pseudostratified columnar:

(Looks like many layers, but is only 1; often ciliated ↓)

Hyaline cartilage:

(Notice the chondrocytes, but not as densely arranged as fibro ↓)

Cardiac muscle:

(Look for those intercalated discs!)

Blood

Simple squamous:

(Pointing to the 1 layer of flattened looking cells ↓)

Nerve tissue

Simple columnar:

(One layer of column shaped cells ↓)

Adipose

Skeletal muscle:

(Striations, but no intercalated discs ↓)

Smooth muscle:

(No striations or discs; spindle shaped)

Bone

In sweat, salivary, and sebaceous gland; in mucous and goblet cells lining the intestinal and respiratory tracts

Exocrine glands

One layer, differing heights (looks like it's many layers, but is not)

Pseudostratified columnar

Easy absorption, diffusion, filtration

Simple squamous

Protects underlying tissues often subjected to abrasion

Stratified squamous

Absorption & secretes mucus and enzymes

Simple columnar

Typically have cilia for propulsion of mucus

Pseudostratified columnar

Release hormones into the bloodstream

Endocrine gland

Thin and flat, several layers

Stratified squamous

Thin and flat, one layer

Simple squamous

Forms external part of skin, extends into openings, directly continuous with skin

Stratified squamous

Tall slender rectangles, one layer

Simple columnar

Makes up serosae of ventral body cavity; forms inner lining of heart and blood vessels, lymphatic vessels, and alveolar walls of lungs

Simple squamous

Found in nasal cavity, trachea, bronchi, and upper respiratory tract in general (ciliated); also males sperm carrying ducts (non-ciliated)

Pseudostratified columnar

Found in gallbladder, stomach, small intestine, large intestine (non-ciliated) and uterus and uterine tubes (ciliated)

Simple columnar

Can withstand great tensile stress when force is applied in ONE direction

Dense regular connective tissue

Avascular, lacks nerve fibers, found between pubic bones (as pubic symphysis) and as intervertebral discs

Fibrocartilage

Support and protection, provides levers for muscle actions, and stores minerals; calcified matrix

Bone

Fluid matrix that carries nutrients, gases, and wastes through arteries and veins

Blood

Avascular, lacks nerve fibers, found at synovial joints (covering ends of long bones) and where the ribs attach to the sternum

Hyaline cartilage

Interwoven network of collagen fibers and fibroblast cells

Dense irregular connective tissue

Makes up tendons (attach muscle to bone) and ligaments (attach bone to bone)

Dense regular connective tissue

Makes up the axial and appendicular skeleton and is well vascularized

Bone

Tightly packed, parallel collagen fibers & fibroblast cells

Dense regular connective tissue

Can withstand tension exerted in MANY directions

Dense irregular connective tissue

Found under the skin in subcutaneous tissue and stores energy

Adipose tissue

Found in dermis of the skin and fibrous capsules of joints

Dense irregular connective tissue

Tensile strength allows it to absorb compressive shock and withstand heavy pressure

Fibrocartilage

Resists compression stress, acts as a cushion, and supports and reinforces throughout the body

Hyaline cartilage

Provides insulation and a reserve source of fuel; commonly called fat

Adipose tissue

Nonstriated involuntary muscle

Smooth muscle tissue

All voluntary muscles of the body (biceps, glutes, etc.)

Skeletal muscle tissue

Membrane that plays a role in body temperature regulation

Cutaneous membrane

Lines body cavities that DO NOT open to the outside of the body

Serous membranes

Propels substances along internal passageways via rhythmic contraction and relaxation

Smooth muscle tissue

Membrane that is adapted for secretion and absorption - always wet with secretions

Mucous membranes

Keratinized stratified squamous epithelium attached to a thick layer of connective tissue

Cutaneous membrane

Striated involuntary muscle

Cardiac muscle tissue

Tissue of the brain and spinal cord

Nerve tissue

Striated voluntary muscle

Skeletal muscle tissue

Lines the pericardial, pleural, and peritoneal cavities

Serous membranes

Membrane found in digestive, respiratory, urinary, and reproductive tracts

Mucous membranes

Found in the walls of the heart

Cardiac muscle tissue

Membrane that secretes serous fluid which reduces friction and lubricates parietal and visceral layers

Serous membranes

Found in the walls of hollow organs such as the esophagus, small intestine, bladder, etc.

Smooth muscle tissue

Tissue that has excitable and non-excitable cells: the excitable cells transmit electrical messages and the non-excitable cells support and protect excitable cells

Nerve tissue

Lines passageways in the body that have external connections (open to the outside of the body)

Mucous membranes
