Surrounding the nucleus and … As seen in the image below, a muscle cell is a compact bundle of many myofibrils. Each myofibril is made of many sarcomeres bundled together and attached end-to-end. A specialized form of the endoplasmic reticulum, known as the sarcoplasmic reticulum, extends in and around these myofibril bundles. The … See more A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins … See more To activate a muscle, the brain sends an impulse down a nerve. The nerve impulse travels down the nerve cells to the neuromuscular junction, where a nerve cell meets a muscle cell. … See more 1. Certain heart defects can be inherited genetically.
