What body region is the brachial located?
The brachialis muscle is located in the upper arm. It lies underneath the biceps muscle. It acts as a structural bridge between the humerus, which is the bone of the upper arm, and the ulna, which is one of the forearm bones. The muscle is innervated by both the musculoskeletal nerve and the radial nerve.
Where is the brachial artery found?
The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm.
How many bones make up the brachial region?
It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles. The nerves of the arm are supplied by one of the two major nerve plexus of the human body, the brachial plexus.
What structure is in the brachial region?
Brachial artery: biceps brachii muscle, triceps brachii muscle, coracobrachialis muscle.
What is the name of upper arm Region bone?
The humerusThe humerus is the single bone of the upper arm, and the ulna (medially) and the radius (laterally) are the paired bones of the forearm.
What is the bone of the forearm called?
Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius).
How many bones are found in the arm or brachial region quizlet?
Arms and forearms (6 bones) - Left and right humerus (2) (arm), ulna (2) and radius (2) (forearm).
What are the 5 parts of the brachial plexus?

What region is elbow?
The elbow is the region between the arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus.
What is the humerus bone?
The humerus is the bone in your upper arm that's located between your elbow and your shoulder.
What is an ulna bone?
The ulna is the longest, thinnest bone of the forearm. It articulates proximally with the trochlea of the humerus and with the head of the radius. Distally it articulates with the ulnar notch of the radius and with an articular disk that separates it from the carpal bones.
What are the two bones in your forearm?
The forearm consists of two bones, the radius and the ulna, with the ulna is located on the pinky side and the radius on your thumb side.
What is the wrist bone called?
carpal bonesYour wrist is made up of eight small bones called the carpal bones, or the carpus. These irregularly shaped bones join your hand to the two long forearm bones: the radius and ulna. The carpal bones are small square, oval, and triangular bones. The cluster of carpal bones in the wrist makes it both strong and flexible.
Where is the mandibular arch?
The mandibular arch lies between the first branchial groove and the stomodeum; from it are developed the lower lip, the mandible, the muscles of mastication, and the anterior part of the tongue. Its cartilaginous bar is formed by what are known as Meckel’s cartilages (right and left) (Fig. 43); above this the incus is developed.
What is the cartilage of the third arch?
The cartilage of the third arch gives origin to the greater cornu of the hyoid bone. The ventral ends of the second and third arches unite with those of the opposite side, and form a transverse band, from which the body of the hyoid bone and the posterior part of the tongue are developed.
What is the first arch of the aortic arch?
The first arch is named the mandibular, and the second the hyoid; the others have no distinctive names. In each arch a cartilaginous bar, consisting of right and left halves, is developed, and with each of these there is one of the primitive aortic arches. The mandibular arch lies between the first branchial groove and the stomodeum;
Which process forms the cheek and lateral part of the upper lip?
From the dorsal ends of the mandibular arch a triangular process, the maxillary process, grows forward on either side and forms the cheek and lateral part of the upper lip. The second or hyoid arch assists in forming the side and front of the neck.
Which cartilages form the thyroid?
The ventral portions of the cartilages of the fourth and fifth arches unite to form the thyroid cartilage; from the cartilages of the sixth arch the cricoid and arytenoid cartilages and the cartilages of the trachea are developed.
Which cartilage is ossified to form the malleus?
The dorsal end of each cartilage is connected with the ear-capsule and is ossified to form the malleus; the ventral ends meet each other in the region of the symphysis menti, and are usually regarded as undergoing ossification to form that portion of the mandible which contains the incisor teeth.
Which direction is the flexor surface of the fore limb?
As a consequence of this rotation the preaxial (radial) border of the fore-limb is directed lateralward, and the preaxial (tibial) border of the hind-limb is directed medialward; thus the flexor surface of the fore-limb is turned forward, and that of the hind-limb backward.
