Anatomy Notes and Terms

Triceps Brachii - It's attachments are the Olecranon process, posterior humerus shaft, and infraglenoid tuberical. When it contracts it causes extention.

The muscles’ stretched starting position means that the individual sarcomeres of her muscles have less overlap

As Jim’s muscles are at maximum demand, his mitochondria are unable to produce the needed ATP through aerobic respiration because oxygen is unable to diffuse fast enough into his muscle fibers. At this time anaerobic

In order to test the passive sufficiency of a bi-articular structure, such as a muscle, both joints which that structure crosses must first be identified. Additionally, the movements of those two joints which will constrain that structure must be identified. Next, one joint must be selected, and placed into the position that may constrain the structure. At the same time, the other joint must be placed in the position which will NOT put further strain on that structure. The selected joint must then be measured for its range of motion. Next, the same must be done with the selected joint, but in contrast, the other joint must be placed in the position which WILL further constrain the bi-articular structure. Once that has been done, the selected joint’s range of motion must be measured once more.

The membranes of neurons at rest are very permeable to _____ but only slightly permeable to _____.

Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.

The quads include the rectus femoris, and the vastus lateralis, intermedius, and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity, and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation, and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the knee joint is the strength of the quads. The only muscle that assists in extension is the tensor fascia lata.

The structure that furnishes the axis for the rotation of the head from side to side is the:

- Anatomy studies the structure of body parts and their relationships to one another. Body structures can be seen, felt, and examined closely.

My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model’s face was quickly appearing, and the proportions of her eyes-to-nose and ear-to-mouth were just right. Proportions of the human face were something I learned in art class, whereas the details in her eyes were something I learned in anatomy class.
