pigs do indeed have a muscle called the biceps brachii. It is one headed though unlike in humans where there are 2 heads.
A biceps is any muscle with two heads.
The "biceps brachii" in the upper arm, for example, has two origins. This is shown in its name, "biceps," which means "two heads." It is attached to the scapula (shoulderblade) in two places
Two
a normal pig has ten billion, five million, and two heads
The prefix bi- means two. In the biceps muscle there are two heads.
Bi means two and as this muscle originates from two heads it is called biceps
Biceps is a muscle that has two heads. It doens't really refer to a single muscle, because there are two biceps muscles. One is the biceps brachii which is one of the flexors of the elbow and the other is the biceps femoris, which extends the hip and flexes the knee.
The triceps muscle is located on the back of the upper arm and has three heads, while the biceps muscle is located on the front of the upper arm and has two heads. The triceps muscle is responsible for extending the arm, while the biceps muscle is responsible for flexing the arm.
That would be your biceps muscle. The "two heads" in question are the muscle's two points of origin: on the coracoid process of the shoulder blade, and the glenoid cavity of the shoulder joint. The word "biceps" comes from the prefix bi-, meaning "two", and the root cap, "head" (the full Latin word for "head" is caput, capitis, n.). To be precise, this biceps is known as biceps brachii, the "biceps of the arm"; there's a second biceps in the thigh known as the biceps femoris.
It tells you the number of origins. "When biceps, triceps, or quadriceps forms part of a muscle's name, you can assume that the muscle has two, three, or four origins, respectively. For example, the biceps brachii muscle of the arm has two origins, or heads."- Human Anatomy & Physiology. Eighth Edition. Elaine N. Marieb page 321
The triceps and biceps are both muscles in the arm, but they have different functions and structures. The triceps are located on the back of the upper arm and are responsible for extending the arm, while the biceps are located on the front of the upper arm and are responsible for flexing the arm. In terms of anatomy, the triceps have three heads or sections, while the biceps have two heads.
1 of each on each arm. Triceps are in the back of the upper arm while the Biceps are in the front. Both of which run from your shoulder to elbow.
