This is mostly filled with parallel collagen bundles with few fibroblasts that are aligned with collagen. It provides strong connections in the musculoskeletal system and allows for strong resistance against force. Some examples of this tissue type are ligaments, tendons, aponeuroses, and corneal stroma.
Elastic Cartilage:
Its major cells are chondrocytes and chondroblasts, with an ECM consisting of Type II collagen, aggrecan, and darker elastic fibers. Its primary function is to provide flexible shape and support of soft tissues. Examples of where it can be found are the external ear, external acoustic meatus, auditory tube, epiglottis, and other laryngeal cartilages.
(White) Adipose Tissue:
Its defining cells are adipocytes that are specialized for energy storage. The adipocytes of white fat are large cells with one big droplet, which pushes the nucleus and the remaining cytoplasm to the cell membrane. It is found in many organs throughout the body (20% of the body weight in adults). It can be found under the skin, around internal organs, and in the central cavity of bones.

The drawing above shows the following types of connective tissue:
– dense regular connective tissue
– elastic cartilage
– adipose tissue
These three drawings were the ones that had clear photographs on the Getaprofessor website. The tissue that appeared most in those photographs was the elastic cartilage.
1. Dense Regular Connective Tissue
– The original photo had a label that the tissue was from a tendon. Tendons attach muscles to bones and/or other structures. Tendons are white in color because they are avascular (or poorly vascularized). This means that they lack blood supply. Though not very clear in the drawing, tendons have parallel fibers as compared to dense irregular connective tissue.
Tendons are found in various parts of the body, most especially in the muscle and skeletal systems. They connect your muscles to your bones in the elbow, knee, and shoulder.

2. Elastic Cartilage
Compared to the previous tissue, tendon, elastic cartilage is more flexible. It can withstand repeated bending. One example of this is our ears. To some degree, we can bend the cartilage in our ears. Just like tendon, cartilage is avascular. Nourishment is provided via diffusion.
In the drawing, there is the perichondrium. The perichondrium is a dense layer of connective tissue that covers the external surface of cartilage. Additionally, it contains blood vessels that strengthen and nourish cartilage by long-range diffusion.
Junqueira’s Basic Histology mentions that there are 2 major types of adipose tissue–white and brown. In the first comment, I mentioned that the adipose tissue in the drawing was white.
White adipose tissue has one large cytoplasmic droplet. On the other hand, brown adipose tissue has multiple droplets interspersed between mitochondria (giving the cell a darker appearance). Brown adipocytes are also smaller than white fat cells.
White adipose tissue is the more common type specialized for fat storage. Brown adipose tissue release heat and functions to warm the blood.
