How many deltoids in body?
There are four deltoid muscles in the body. Anterior and posterior left. Anterior and posterior right.
What joint is at deltoid muscle?
The deltoid muscle is the big muscle on the shoulder. It has three parts; the front or anterior, middle and back or posterior. It involves the shoulder joint.
Where are the origins and insertions of the deltoids muscles?
The deltoid muscle looks like a large "D" covering the shoulder. There are three parts to it: The anterior deltoid which is commonly called front delts, The lateral deltoids or side delts, and the posterior deltoid or rear delts. The anterior deltoid's (front delts') origin is the clavicle, the lateral's (side delts') origin is the acromion process of the scapula and the posterior's (rear delts') origin is the spine of the scapula. The insertion for all is the deltoid tuberosity on the humerus.
What ligaments make up the deltoid ligament?
The deltoid ligament is composed of four ligaments: anterior tibiotalar ligament, tibiocalcaneal ligament, posterior tibiotalar ligament, and tibionavicular ligament. These ligaments provide stability to the inner side of the ankle joint.
anterior and posterior relation of both the kidny?
The kidneys have their anterior and posterior surfaces. The foremost surface countenances towards the front stomach wall, while the back posterior surfaces confronting the posterior stomach wall. These surfaces are isolated by the edges of the kidney, which are the significant convexity horizontally, and minor concavity medially.

What is the Prime mover for abduction?
the supraspinatus ...I think Deltoid muscle(acromial part)
Which direction is the opposite of posterior?
....behind/back and antonym would be anterior - in front/front
Do these animals have an anterior or a posterior?
What animals? As anterior means front and posterior means back, then most-if not all animals have a front and back, or an anterior and posterior. They are usually characterized by a mouth(anterior) or rectum/anus (posterior).
What do anterior and middle cerebral arteries arise from?
The anterior and posterior cerebral arteries are both branches of the internal carotid artery
What are the deltoid muscle fibers separated into?
The deltoid muscle fibers are separated into three distinct anatomical regions: the anterior (front), lateral (middle), and posterior (rear) fibers. Each region has different functions; the anterior fibers primarily assist in shoulder flexion and internal rotation, the lateral fibers are responsible for shoulder abduction, and the posterior fibers facilitate shoulder extension and external rotation. This organization allows for a wide range of shoulder movements.
