In Biology, a tissue is just a group of cells that share the same origin and work together to do something. It's a level of organization. An erector muscle fulfills those requirements, so it can be considered a tissue.

Muscle that appears banded?

The muscle that appears banded is skeletal muscle. Its banded appearance, known as striations, is due to the arrangement of muscle fibers and the presence of overlapping sarcomeres containing actin and myosin filaments. Skeletal muscle is responsible for voluntary movements in the body.


Can move an animals skeleton by contracting and relaxing?

Yes, muscles can move an animal's skeleton by contracting and relaxing. When a muscle contracts, it pulls on the bones it is attached to, causing movement at a joint. Alternating contraction and relaxation of muscles allows for coordinated movement of the skeleton.


Muscle tissue consists of cells that are highly specialized for the function of?

Muscle tissue consists of cells that are highly specialized for the function of contraction. These cells contain proteins that allow them to generate force and movement. Muscle tissue can be classified into three types: skeletal, cardiac, and smooth muscle, each with unique properties related to their specific functions.


What are the four primary tissues in adult organ?

Epithelial Tissue- this tissue covers any bodily surface including organs, body cavities, and glands. There are subcategories of Epithelial Tissue, which are Squamous (pavement) , Simple Columnar, Simple Cuboidal, Glandular, Stratified, and Ciliated Columnar. The main functions of epithelial tissue are sensation, absorption, protection, cleaning, reduction of friction, excretion, diffusion, and secretion. Connective Tissue- this tissue forms blood, cartilage, and bone. It is classified into dense connective, loose connective, reticular, elastic, and adipose. Muscle- contractile tissue that causes movement in an organism as well as internal functions. The three types of muscle tissue are skeletal, smooth, and cardiac. Nervous Tissue- this tissue is responsible for sending and receiving messages from muscle tissue to the brain. Nervous tissue is composed of neurons.


Muscle spasms of the back often are due to the erector spinae contraction?

Yes, muscle spasms in the back can be caused by the erector spinae muscles contracting involuntarily. This can occur due to factors such as muscle fatigue, poor posture, or injury. Stretching, massage, and strengthening exercises can help alleviate and prevent these spasms.
